The manufacturer of color televisions can sell 1900 sets to his dealers at $575 each. If the price is $470, he can sell 2600 sets. The total cost of producing x television sets is C(x)=3300+608x−0.09x^2. Assuming the demand function is linear, find the price per set that will maximize profit. Round your answer to the nearest cent, if necessary.

Answers

Answer:

  $545

Step-by-step explanation:

Finding the price that maximizes profit requires several steps. We need the demand function that tells quantity sold in terms of selling price. With this, we can express the cost and revenue functions in terms of selling price. The profit will be the difference between revenue and cost.

__

demand

The demand (q) is said to be a linear function of price (p). The equation for that can be written ...

  q(p) = (q2 -q1)/(p2 -p1)(p -p1) +q1 . . . . . for two points (p1, q1) and (p2, q2)

Using the given demand points, this can be ...

  q(p) = (1900 -2600)/(575 -470)(p -470) +2600

  q(p) = -20/3(p -470) +2600

  q(p) = -20/3p +5733 1/3

__

cost

The cost function in terms of selling price can be found by substituting the q(p) equation for x in c(x). For the purpose of finding the maximum profit, we only need the marginal cost function:

  c(q(p))' = c'(q(p))·q'(p) = (608 -0.18(q(p)))·(-20/3) = (608 -0.18(-20/3p +5733 1/3))(-20/3)

  c'(p) = -8p +2826 2/3

__

revenue

As with cost, the function we need for finding the maximum profit is the marginal revenue function. Revenue is the product of price and demand, so the marginal revenue is ...

  r(p) = p·q(p)

  r'(p) = q(p) +p·q'(p) = (-20/3p +5733 1/3) +p(-20/3)

  r'(p) = -40/3p +5733 1/3

__

maximum profit

The maximum profit is found where the marginal profit is zero. In turn, that is found where the difference between marginal revenue and marginal cost is zero:

  P = R -C

  P'(p) = 0 = r'(p) -c'(p) = (-40/3p +5733 1/3) -(-8p +2826 2/3)

  0 = -16/3p +2906 2/3

  16p = 8720 . . . . . multiply by 3, add 16p

  p = 545 . . . . . . . price for maximum profit

The price per set that maximizes profit is $545.00.

In an arithmetic sequence of numbers a1 = -4 and a6 = 46. Which of the following is the value of a12?

Answers

Answer:

a₁₂ = 106

Step-by-step explanation:

Given

a₁ (first term) = -4a₆ = 46

Formula for nth term

aₙ = a₁ + (n - 1)d

Using that to expand a₆ and find d

a₆ = a₁ + (n - 1) d46 = -4 + (6 - 1)d50 = 5dd = 10

Finding a₁₂

a₁₂ = a₁ + 11da₁₂ = -4 + 11(10)a₁₂ = 110 - 4a₁₂ = 106

Answer:

[tex]a_{12}=106[/tex]

Step-by-step explanation:

Arithmetic sequence

General form of an arithmetic sequence: [tex]a_n=a+(n-1)d[/tex]

where:

[tex]a_n[/tex] is the nth terma is the first termd is the common difference between terms

Given:

[tex]a_1=-4[/tex][tex]a_6=16[/tex]

To find the common difference (d), substitute the given values into the general formula and solve:

[tex]\begin{aligned}\implies a_6=(-4)+(6-1)d & =46\\ 5d-4 & =46\\ 5d & = 50\\ d & =10\end{aligned}[/tex]

Therefore, the equation for the nth term is:

[tex]\begin{aligned}a_n &=-4+(n-1)10\\& =10n-14 \end{aligned}[/tex]

To find the 12th term, substitute n = 12 into the equation:

[tex]\implies a_{12}=10(12)-14=106[/tex]

Answer:

70/100 ; 3/10 ; 50/100

Step-by-step explanation:

You need to multiply numbers to make them equivalent.

1st Question:

7/10 has to multiply by 10/10 because the denominator of the other one is 100 and 10 x 10 is 100.

7 x 10 = 70

70/100 shall be your answer.

2nd Question:

This time you need to find your starting point.

A way to do this is to divide/simplify the fraction in order to make it equivalent.

You need to divide by 10 because your quotient and denominator at your starting point is 10 and 100/10 is 10.

30 divided by 10 is 3

Your Answer for this one is: 3/10

3rd Question:

Same thing as the 1st one.

Multiply by 10.

5 x 10 = 50

If you subtract then it would be 13/20. The decimal form if 0.65. There are no numbers we can divide by the top and bottom so it should be 13/20.

Hey there!

41/40 - 3/8

= 41/40 - 3 × 5 / 8 × 5

= 41/40 - 15/40

= 41 - 15 / 40 - 0

= 26 / 40

= 26 ÷ 2 / 40 ÷ 2

= 13 / 20


Therefore, your answer is: 13/20

to the right is P(z> Z)

so P(z>Z) = 0.9909

P(z< Z) = 1- 0.9909 = 0.0091

Closest values from a z-table

P(z< -2.37) = 0.00889 (-0.00011 away)

p(z< -2.36) = 0.00914 (+0.00014 away)

fifty million of 94 million households watched the last episode of a popular television show. What percentage of households were not watching the show?

Answers

The percentage of households that were not watching the show were 46.81%.

Step-by-step explanation:

In this case, we need to find the percentage of households that don´t watch the show. First, we need to know how much households don´t watch the show, this is:

[tex]94,000,000-50,000,000=44,000,000[/tex]

So, the households that were not watching the show were 44 million.

Now we can calculate the percentage, to find a percentage we use a division and to introduce the percentage units we multiply by 100.

[tex]\frac{44,000,000}{94,000,000}[/tex] × [tex]100=46.81[/tex]

The percentage of households that were not watching the show were 46.81%.

Sophia goes to an icecream shop to get a medium ice cream that costs $4.50, Sophia only has $6.40 and toppings are $0.75 each. Write an inequality to find how many toppings Sophia can get .

Answers

Answer:

x ≤ 2

Step-by-step explanation:

4.5 = medium ice cream

0.75x = toppings, x = amount of toppings

Sophia has $6.4, so 4.5+0.75x has to be less or equal to that.

4.5 + 0.75x ≤ 6.4, solve

0.75x ≤ 1.9

x ≤ 2 8/15

BUT you cannot get half a topping or a fraction of a topping,

so, x ≤ 2 toppings.

Sophia can get 2 or less toppings.

Answers

Anything withdrawn you subtract. Then, you know the total and you know what you had. Subtract total from what you had and you will see the change.

1735.97-100=1635.97

1668.71-1635.97=32.74



Natalie Albert deposited checks totaling $1,735,97 into her savings account, she withdrew $100.00 while depositing some coins. If her total deposit was $1,668.71 then Natalie deposited $32.74 in coins.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

Let's call the amount Natalie deposited in coins "x".

We know that her total deposit was $1,668.71,

so we can write an equation:

1,735.97 - 100.00 + x = 1,668.71

Simplifying, we get:

1,635.97 + x = 1,668.71

Subtracting 1,635.97 from both sides, we get:

x = 32.74

Therefore, Natalie deposited $32.74 in coins.
