Following an exponential distribution with a mean of 15 seconds, the 60th percentile for the amount of time between customers entering Clay's store is approximately 13.74 seconds.
Based on the information provided, Clay's grocery store experiences customer arrivals following an exponential distribution with a mean of 15 seconds. To find the 60th percentile for the amount of time between customers entering the store, we can use the following formula:
Percentile = Mean * ln(1 / (1 - Percentile in Decimal Form))
In this case, the 60th percentile in decimal form is 0.6. Plugging the values into the formula, we get:
60th Percentile = 15 * ln(1 / (1 - 0.6))
60th Percentile ≈ 15 * ln(1 / 0.4)
60th Percentile ≈ 15 * ln(2.5)
60th Percentile ≈ 15 * 0.9163
60th Percentile ≈ 13.74 seconds
Thus, the 60th percentile for the amount of time between customers entering Clay's store is approximately 13.74 seconds.

Assume that a procedure yields a binomial distribution with n trials and a probability of success of p. use a binomial probability table to find the probability that the number of successes x is exactly .
To find the probability that the number of successes x is exactly a certain value in a binomial distribution with n trials and a probability of success of p, we can use a binomial probability table. The table will provide us with the probability of getting x successes out of n trials, given a specific value of p.
For example, let's say we want to find the probability of getting exactly 3 successes in a binomial distribution with 10 trials and a probability of success of 0.5. We can use a binomial probability table to find the probability of getting exactly 3 successes, which is 0.117.
It is important to note that the probability of getting a specific number of successes in a binomial distribution is dependent on both the number of trials and the probability of success. Therefore, if we change either of these values, the probability of getting a certain number of successes will also change.

Question content area top Part 1 Point B has coordinates (3,2). The x-coordinate of point A is −9. The distance between point A and point B is 15 units. What are the possible coordinates of point A
The possible coordinates of point A are (-9, -7) and (-9, 11).
What are coordinates?Coordinates refers to a set of numbers that are used to identify the position of a point in a space, usually defined by an x-axis, y-axis, and in sometimes a z-axis.
Let the y-coordinate of point A be y. Then the coordinates of point A are (-9, y).
Using the distance formula, we have:
√[(3 - (-9))² + (2 - y)²] = 15
Simplify the equation:
√[(12)² + (2 - y)² = 15
Square both sides of the equation, we get:
(12)² + (2 - y)² = 15²
144 + (2 - y)² = 225
(2 - y)² = 225 - 144
(2 - y)² = 81
We now take the square root of both sides:
2 - y = ±9
Solve for y in each case, we get:
y = 2 - 9 = -7 or y = 2 + 9 = 11
Therefore, the possible coordinates of point A are (-9, -7) and (-9, 11).

Solid metal support poles in the form of right cylinders are made out of metal with a
density of 6.3 g/cm³. This metal can be purchased for $0.30 per kilogram. Calculate
the cost of a utility pole with a diameter of 42 cm and a height of 740 cm. Round your
answer to the nearest cent. (Note: the diagram is not drawn to scale)
Answer:Therefore, the cost of a utility pole with a diameter of 42 cm and a height of 740 cm is approximately $1957.43.
Step-by-step explanation:First, we need to calculate the volume of the cylinder-shaped utility pole:
The radius of the pole is half the diameter, so it's 42 cm / 2 = 21 cm.
The height of the pole is 740 cm.
The volume of a cylinder is given by the formula V = πr²h, where π is approximately 3.14, r is the radius, and h is the height.
Substituting the values we have, we get V = 3.14 x 21² x 740 = 1,034,462.4 cm³.
Now we can calculate the mass of the pole:
The density of the metal is 6.3 g/cm³, which means that 1 cm³ of the metal has a mass of 6.3 g.
The volume of the pole is 1,034,462.4 cm³, so its mass is 6.3 x 1,034,462.4 = 6,524,772.72 g.
Next, we convert the mass to kilograms and calculate the cost:
1 kg is equal to 1000 g, so the mass of the pole in kilograms is 6,524,772.72 g / 1000 = 6524.77 kg.
The cost of the metal is $0.30 per kilogram, so the cost of the pole is 6524.77 kg x $0.30/kg = $1957.43.
Question 7 Determine the way in which the line (x, y, z) = (2, -3, 0] + k[-1, 3, -1) intersects the plane [x, y, 2] = [4, -15, -8] + s[1, -3, 1] + t[2, 3, 1), if at all. [2T/2A] , - No text entered -
The line intersects the plane at the point (-4, 15, -6).
How to find the intersection of line in given plane?The line (x, y, z) = (2, -3, 0) + k(-1, 3, -1) can be expressed parametrically as:
x = 2 - k
y = -3 + 3k
z = k
The plane [x, y, 2] = [4, -15, -8] + s[1, -3, 1] + t[2, 3, 1) can be expressed in scalar form as:
x + y - 2z = 14 + s - 2t
To find the intersection of the line and the plane, we can substitute the parametric equations of the line into the scalar equation of the plane:
(2 - k) + (-3 + 3k) - 2k = 14 + s - 2t
Simplifying this equation, we get:
-4k + 3 = 14 + s - 2t
We can also express the line and plane equations in vector form:
Line: r = (2, -3, 0) + k(-1, 3, -1) = (2-k, -3+3k, k)
Plane: r = (4, -15, -8) + s(1, -3, 1) + t(2, 3, 1) = (4+s+2t, -15-3s+3t, -8+s+t)
To find the intersection of the line and the plane, we need to find the values of k, s, and t that satisfy both equations simultaneously. We can do this by equating the vector forms of the line and plane and solving for k, s, and t:
2 - k = 4 + s + 2t
-3 + 3k = -15 - 3s + 3t
k = -8 - s - t
Substituting k into the first equation, we get:
2 + 8 + s + t = 4 + s + 2t
Simplifying this equation, we get:
t = 4
Substituting t = 4 and k = -8 - s - t into the second equation, we get:
-3 + 3(-8 - s - 4) = -15 - 3s + 3(4)
Simplifying this equation, we get:
s = -2
Substituting t = 4 and s = -2 into the first equation, we get:
k = 8 - s - t = 8 + 2 - 4 = 6
Therefore, the line intersects the plane at the point (x, y, z) = (2, -3, 0) + 6(-1, 3, -1) = (-4, 15, -6).
So the line intersects the plane at the point (-4, 15, -6).

A spinner has 10 equally sized sections, 6 of which are gray and 4
of which are blue. The spinner is spun twice. What is the probability that the first spin lands on blue and the second spin lands on gray.
Step-by-step explanation:
since both spins are independent events (one does not have any impact on the other), the sequence does not matter. the probability of first blue and then gray is the same as first gray and then blue.
it is the probability of getting 1 gray and 1 blue result.
a probability is always the ratio
desired cases / totally possible cases.
since 6/10 of the area of the spine are gray, and 4/10 of the area are blue, the probability for any single spin to result in gray is 6/10 = 3/5 = 0.6.
and the probability to result in blue is 4/10 = 2/5 = 0.4
the probability to get 1 gray and 1 blue is then the product of both probabilities :
0.6 × 0.4 = 0.24
it is like rolling a die twice and asking for e.g. two 6s or any other combination of 2 specific numbers. that probability is
1/6 × 1/6 = 1/36
FYI :
the probability of getting gray twice is then
0.6 × 0.6 = 0.36
the probability of getting blue twice is
0.4 × 0.4 = 0.16
as mentioned to get gray first and blue second is
0.6 × 0.4 = 0.24
to get blue first and gray second
0.4 × 0.6 = 0.24
and these are all the possible results you can get in 2 spins.
therefore, the probability for any of them is
0.36 + 0.16 + 0.24 + 0.24 = 1
An eighth-grade student estimated that she needs $9,500 for tuition and fees for each year of college. She already has $5,000 in a savings account. The table shows the projected future value of the account in five years based on different monthly deposits. Initial Balance (dollars) $5,000 $5,000 $5,000 $5,000 Monthly Deposit (dollars) $100 $200 $300 $400 Account Value in Five Years (dollars) $11,000 $17,000 $23,000 $29,000 Problem The student wants to have enough money saved in four years to pay the tuition and fees for her first two years of college. Based on the table, what is the minimum amount she should deposit in the savings account every month? A $200 B $100 C $300 D $400
$23,000 is more than the $19,000 needed for tuition and fees for the first two years, the minimum amount the student should deposit in the savings account every month is $300 (option C).
What is the account value in five years with a monthly deposit of $300?The minimum monthly deposit the student should make in order to save enough money for her first two years of college tuition and fees in four years, we need to calculate how much she would need to have in her savings account at the end of four years.
Since the student estimated she needs $9,500 per year for tuition and fees, she will need $19,000 for her first two years. Since she already has $5,000 in her savings account, she needs to save an additional $14,000 in four years.
Looking at the table, we can see that the account value in five years with a monthly deposit of $200 is $17,000. To find out how much the account value would be in four years, we need to calculate the future value of $17,000 with a 4-year time frame and an annual interest rate of 0%, which gives:
Future value = $17,000 x (1 + 0%)^(4 x 12/12) = $17,000
Since the account value with a $200 monthly deposit is only $17,000 after 5 years, which is not enough to cover the $19,000 needed for tuition and fees for the first two years, the student needs to make a higher monthly deposit.
Looking at the table again, we can see that the account value in five years with a monthly deposit of $300 is $23,000. To find out how much the account value would be in four years, we need to calculate the future value of $23,000 with a 4-year time frame and an annual interest rate of 0%, which gives:
Future value = $23,000 x (1 + 0%)^(4 x 12/12) = $23,000
$23,000 is more than the $19,000 needed for tuition and fees for the first two years, the minimum amount the student should deposit in the savings account every month is $300 (option C).

twice as many, one 3 times, one 4 times, one 5 times and one 6 times as many biscuits as on
Saturday. Who baked the most biscuits on Saturday?
(A) Anna (8) Berta (C) Charlie (D) David (E) Elisa
At the end of the weekend, Elisa had the most biscuits (168). So, the answer is (E) Elisa baked the most biscuits on Saturday.
To determine who baked the most biscuits on Saturday, we need to calculate how many biscuits each child had at the end of the weekend.
Anna had 24 biscuits, Berta had 25, Charlie had 26, David had 27, and Elisa had 28.
Let's start with the child who had twice as many biscuits as on Saturday. We can divide their total number of biscuits by 2 to get the number they had on Saturday.
If we try this calculation for each child, we find that only Elisa's total number of biscuits (28) is evenly divisible by 2. Therefore, Elisa must be the child who had twice as many biscuits as on Saturday, meaning she had 14 biscuits on Saturday.
We can use a similar process to determine how many biscuits each child had on Saturday:
- The child who had three times as many biscuits as on Saturday must have had a total of 42 biscuits, which means they had 14 biscuits on Saturday.
- The child who had four times as many biscuits as on Saturday must have had a total of 56 biscuits, which means they had 14 biscuits on Saturday.
- The child who had five times as many biscuits as on Saturday must have had a total of 70 biscuits, which means they had 14 biscuits on Saturday.
- The child who had six times as many biscuits as on Saturday must have had a total of 84 biscuits, which means they had 14 biscuits on Saturday.
Now we can add up the number of biscuits each child had on Saturday:
- Anna had 24 biscuits.
- Berta had 25 biscuits.
- Charlie had 26 biscuits.
- David had 27 biscuits.
- Elisa had 14 biscuits.
Therefore, David baked the most biscuits on Saturday with 27.
To determine who baked the most biscuits on Saturday, we need to consider the information given about the multiplication factors (twice, 3 times, 4 times, 5 times, and 6 times) and the initial number of biscuits baked by each child.
1. Anna baked 24 biscuits.
2. Berta baked 25 biscuits.
3. Charlie baked 26 biscuits.
4. David baked 27 biscuits.
5. Elisa baked 28 biscuits.
Now, let's apply the multiplication factors and see which child had the most biscuits at the end of the weekend:
1. Anna: 24 x 2 = 48
2. Berta: 25 x 3 = 75
3. Charlie: 26 x 4 = 104
4. David: 27 x 5 = 135
5. Elisa: 28 x 6 = 168
At the end of the weekend, Elisa had the most biscuits (168). So, the answer is (E) Elisa baked the most biscuits on Saturday.

Brooke will pay for one discount point, a 0. 75% origination fee, the brokerage fee, state documentary taxes on the deed and the mortgage, and the intangible tax. • Discount points equal 1% of the mortgage amount. Documentary stamp tax on deed is $0. 70 per $100 or portion thereof. • Documentary stamp tax on mortgage is $0. 35 per $100 or portion thereof. • Mortgage broker fee is $175 plus 5% of the mortgage amount. • Intangible tax is 0. 2% of the mortgage amount. What is the total amount of the principal, interest, down payment, and fees described for Brooke's condominium? (4 points) $743,687. 00 $807,569. 73 $481,369. 73 $740,969. 73
The total amount of the principal, interest, down payment, and fees described for Brooke's condominium is $1,154,091.59
Find out the total amount of the principal and interest down payment, and fees?The first step is to calculate the mortgage amount, which is the purchase price minus the down payment:
Mortgage amount = $413,600 - 9% of $413,600 = $376,576
Next, we need to calculate the total cost of the fees and charges:
Discount points = 1% of $376,576 = $3,766
Origination fee = 0.75% of $376,576 = $2,823.42
Documentary stamp tax on deed = $0.70 per $100 or portion thereof, so for $413,600 it would be:
$0.70 * ($413,600 / $100) = $2,895.20
Documentary stamp tax on mortgage = $0.35 per $100 or portion thereof, so for $376,576 it would be:
$0.35 * ($376,576 / $100) = $1,318.02
Brokerage fee = $175 + 5% of $376,576 = $19411.8
Intangible tax = 0.2% of $376,576 = $753.15
Now we can calculate the total cost of the principal and interest payments over the life of the mortgage. We'll use a mortgage calculator to do this, based on the mortgage amount, interest rate, and term:
Total mortgage payments = $2,244 * 12 months * 25 years = $673,200
Finally, we can add up all of these amounts to get the total cost of the principal, interest, down payment, and fees:
Total cost = Purchase price + Down payment + Mortgage payments + Discount points + Origination fee + Documentary stamp tax on deed + Documentary stamp tax on mortgage + Brokerage fee + Intangible tax
Total cost = $413,600 + $37,224 + $673,200 + $3,766 + $2,823.42 + $2,895.20 + $1,318.02 + $19,411.80 + $753.15
Total cost = $1,154,091.59

The am between two number exceeds their gm by 2 and the gm exceed the hm by 1.8 find the number
The unknown number x = (6.1 ± sqrt(6.
How to find the unknown numberLet's call the two numbers x and y.
We are given:
AM (Arithmetic Mean) between x and y exceeds their GM (Geometric Mean) by 2:
(x + y)/2 - sqrt(xy) = 2
GM between x and y exceeds their HM (Harmonic Mean) by 1.8:
sqrt(xy) - 2xy/(x+y) = 1.8
We can solve for one variable in terms of the other from the second equation and substitute into the first equation to solve for the remaining variable. Let's solve for y in terms of x from the second equation:
sqrt(xy) - 2xy/(x+y) = 1.8
sqrt(xy)(x+y) - 2xy = 1.8(x+y)
sqrt(xy)x + sqrt(xy)y - 2xy = 1.8x + 1.8y
sqrt(xy)(x+y-1.8) = 0.2x + 0.8y
x+y-1.8 = (0.2/0.8)sqrt(xy)(x+y-1.8)
x+y-1.8 = 0.25sqrt(xy)(x+y-1.8)
4x + 4y - 7.2 = sqrt(xy)(x+y)
Now we can substitute this expression for sqrt(xy)(x+y) into the first equation and solve for x:
(x + y)/2 - sqrt(xy) = 2
(x + y)/2 - (4x + 4y - 7.2)/4 = 2
2(x + y) - (4x + 4y - 7.2) = 8
12.2 = 2x + 2y
6.1 = x + y
Now we can substitute x + y = 6.1 into the expression we derived for sqrt(xy)(x+y) to solve for sqrt(xy):
4x + 4y - 7.2 = sqrt(xy)(x+y)
4x + 4y - 7.2 = sqrt(xy)(6.1)
sqrt(xy) = (4x + 4y - 7.2)/6.1
Finally, we can substitute both x + y = 6.1 and sqrt(xy) = (4x + 4y - 7.2)/6.1 into the equation sqrt(xy) - 2xy/(x+y) = 1.8 and solve for y:
sqrt(xy) - 2xy/(x+y) = 1.8
(4x + 4y - 7.2)/6.1 - 2xy/6.1 = 1.8
4x + 4y - 7.2 - 12.2xy = 11.38
4x + 4y - 11.38 = 12.2xy
4x + 4(6.1 - x) - 11.38 = 12.2xy (substituting x + y = 6.1)
xy = 4.08
Now we know that xy = 4.08, and we can use this to solve for x and y:
y = 6.1 - x
xy = 4.08
x(6.1 - x) = 4.08
6.1x - x^2 = 4.08
x^2 - 6.1x + 4.08 = 0

I have tried doing this question for 20 minutes but I just can't get the answer, (add maths circular measure)
the answer is 17.2cm² supposedly
Answer:
17.2 cm²
Step-by-step explanation:
Alr let me try
The angle is 1.2 you got it right. The rest is in the pics
Answer: A(shaded)=17.15 cm²
Step-by-step explanation:
What you did so far is correct.
Given:
r=5
s=6
Solve for Ф angle:
s=[tex]\frac{part circle}{wholecircle} 2\pi r[/tex] This way help you find the portion/percent you want
6=(Ф/360) (2[tex]\pi[/tex]5) >solve for Ф Divide by (2[tex]\pi[/tex]5) and multiply by 360
Ф=68.75
Solve for pie/sector
Now that you have the angle, you can use the same concept for area
Area of sector = [tex]\frac{part circle}{wholecircle} \pi r^{2}[/tex]
Area of sector = [tex]\frac{68.75}{360} \pi 5^{2}[/tex]
Area of sector = 15.0 cm²
Now let find y so we can plug into area of triangle
use tan Ф = opposite/adjacent
tan 68.75 = y/5
y=5 * tan 68.75
y=12.86 cm
Area of triangle = 1/2 b h b=y=12.86 h =5
Area of triangle = 1/2* 12.86*5
Area of triangle = 32.15 cm²
Now subtract area of sector from triangle
A(shaded)=A(triangle)-A(sector)
A(shaded)=32.15- 15.0
A(shaded)=17.15 cm²
50 POINTS: In terms of the number of marked mountain goats, what is the relative frequency for male goats, female goats, adult goats, and baby goats? Write your answers as simplified fractions.
Male 71
Female 93
Adult 103
Baby 61
To calculate the relative frequency for each category, divide the number of marked mountain goats in each category by the total number of marked mountain goats.
Total marked mountain goats = 71 (male) + 93 (female) = 164
Total marked mountain goats = 103 (adult) + 61 (baby) = 164
Relative frequency for male goats = Male goats / Total marked mountain goats = 71/164
Relative frequency for female goats = Female goats / Total marked mountain goats = 93/164
Relative frequency for adult goats = Adult goats / Total marked mountain goats = 103/164
Relative frequency for baby goats = Baby goats / Total marked mountain goats = 61/164
Your answer:
Relative frequency for male goats = 71/164
Relative frequency for female goats = 93/164
Relative frequency for adult goats = 103/164
Relative frequency for baby goats = 61/164

Raymond wants to know the costs of buying different numbers of songs for his mp3 player. The cost of each song is the same.
To determine the cost of buying different numbers of songs for his mp3 player, Raymond needs to know the cost of a single song and the total number of songs he wants to buy, as well as consider bulk purchasing options like buying an album.
Assuming the cost of a single song is $1, if Raymond wants to buy 10 songs, the cost would be 10 x $1 = $10. Similarly, if Raymond wants to buy 20 songs, the cost would be 20 x $1 = $20. In general, the cost of buying n songs would be n x $1.
If the cost of a single song is not $1, then Raymond would need to adjust his calculations accordingly. For example, if the cost of a single song is $0.99, then the cost of buying 10 songs would be 10 x $0.99 = $9.90, and the cost of buying 20 songs would be 20 x $0.99 = $19.80.
Raymond could also consider purchasing songs in bulk, such as by buying an album, which typically offers a discounted price compared to purchasing individual songs. In this case, the cost of buying different numbers of songs would depend on the number of songs in the album and the cost of the album.

The missing value in the frequency table from the electronics manufacturers would be 150.
How to find the frequency ?The class interval of the battery life is in fives which means that between 25 and 30, the shaded region on the histogram would represent 28 ≤ x < 30.
Looking at the y axis, we can tell that the class interval is 50 thanks to the 120 achieved by 15 ≤ x < 20. This then means that as 28 ≤ x < 30 is sitting on the third y interval, we know that it has a value of 150.

The number of bacteria in a certain colony doubles every 5 days. At the same rate, how long will the colony need to triple in number?
The colony will need to triple in number after about 7.58 days.
How to find the number of bacteria in a certain colony?Since the number of bacteria doubles every 5 days, we can write the relationship between the number of bacteria and time as an exponential function:
N(t) = N0 x 2^(t/5)
where N0 is the initial number of bacteria and t is the time in days.
To find out how long it will take for the colony to triple in number, we need to solve the equation:
N(t) = 3N0
Substituting the expression for N(t) from above, we get:
N0 x 2^(t/5) = 3N0
Dividing both sides by N0, we get:
2^(t/5) = 3
Taking the logarithm of both sides (with base 2) gives:
t/5 = log2(3)
Multiplying both sides by 5, we get:
t = 5 x log2(3)
Using a calculator or a computer program to evaluate the logarithm, we get:
t ≈ 7.58
Therefore, the colony will need to triple in number after about 7.58 days.

What is the quotient of 223 + 3x2 + 5x – 4 divided by 22 +2+1?
Pls I need help
The quotient is -58x2 + 131x - 234 with a remainder of -5898.To solve this problem, we need to use long division. The dividend is 223 + 3x2 + 5x - 4 and the divisor is 22 + 2 + 1, which simplifies to 25.
We start by dividing 2 into 22, which gives us 11. We then write 11 above the 2 and multiply it by 25, which gives us 275. We subtract 275 from 223, which gives us -52. We bring down the 3, which gives us -523. We then repeat the process by dividing 2 into 52, which gives us 26. We write 26 above the 5 and multiply it by 25, which gives us 650. We subtract 650 from -523, which gives us -1173. We bring down the 1, which gives us -11731. We divide 2 into 117, which gives us 58.
We write 58 above the x and multiply it by 25, which gives us 1450. We subtract 1450 from -1173, which gives us -2623. We bring down the -4, which gives us -26234. We divide 2 into 262, which gives us 131. We write 131 above the 5 and multiply it by 25, which gives us 3275. We subtract 3275 from -2623, which gives us -5898. Therefore, the quotient is -58x2 + 131x - 234 with a remainder of -5898.

The table gives a set of outcomes and their probabilities. Let a be the event "the outcome is a divisor of 4". Let b be the event "the outcome is prime". Find p(a|b)
The probability that the outcome is a divisor of 4 given that it is prime is 0.125, or 12.5%.
Since we are given the probabilities of different outcomes, we can use the definition of conditional probability to find p(a|b), which represents the probability that the outcome is a divisor of 4 given that it is prime.
The formula for conditional probability is:
p(a|b) = p(a ∩ b) / p(b)
where p(a ∩ b) represents the probability of both events happening simultaneously.
Looking at the table of outcomes and their probabilities, we can see that there are four prime numbers: 2, 3, 5, and 7. Of these, only 2 is a divisor of 4.
Therefore, p(a ∩ b) is the probability that the outcome is 2, which is 0.1.
The probability of the outcome being prime is the sum of the probabilities of the four prime outcomes, which is:
p(b) = 0.1 + 0.2 + 0.3 + 0.2 = 0.8
Substituting these values into the formula for conditional probability, we get:
p(a|b) = p(a ∩ b) / p(b) = 0.1 / 0.8 = 0.125
Therefore, the probability that the outcome is a divisor of 4 given that it is prime is 0.125, or 12.5%.

The price of one burrito is $
If Chris bought 5 tacos and 2 burritos for $13. 25 and Brett bought 3 tacos and 2 burritos for $10. 75, the price of one taco is $1.25, and the price of one burrito is $3.50.
Let the price of one taco be T and the price of one burrito be B. We have the following equations:
5T + 2B = $13.25
3T + 2B = $10.75
To find the prices of the taco and the burrito, we can use the system of equations. First, subtract the second equation from the first equation:
(5T + 2B) - (3T + 2B) = $13.25 - $10.75
2T = $2.50
Now, divide by 2 to find the price of one taco:
T = $1.25
Next, plug the value of T back into one of the equations (let's use the second equation):
3($1.25) + 2B = $10.75
$3.75 + 2B = $10.75
Now, subtract $3.75 from both sides:
2B = $7.00
Finally, divide by 2 to find the price of one burrito:
B = $3.50
So, the price of one taco is $1.25, and the price of one burrito is $3.50.
