Answer:
Stephanie has more than $900
Step-by-step explanation:
Represent the unknowns: a for Alexandra and s for Stephanie.
Then a + s > $2,500, and a = s + $700.
Substituting the latter into the former equation, we get:
(s + $700) + s > $2,500, or
2s > $1800
Then s > $900; Stephanie has more than $900.

The following scatter plot shows the correlation between the number of hours twelve teenagers spent in the mall and the number of dollars they spent on food or drinks while at the mall. Use the line of best fit to estimate how much money a teenager will spend on food if he or she is at the mall for three hours.
$9
$11
$7
$5
The equation of the line of best fit is an illustration of a linear function
The teenager would spend $9 on food if he or she is at the mall for three hours.
How to determine the amount spent on food?
The equation of the line of best fit is given as:
y = 2x + 3
When the teenager spends 3 hours in the mall, it means that:
x = 3
So, we have:
y = 2 * 3 + 3
Evaluate the product
y = 6 + 3
Evaluate the sum
y = 9
Hence, the teenager would spend $9 on food if he or she is at the mall for three hours.

Find the surface area of the prism.
The prism shown consists of 6 parallelograms and the surface area of the prism shown in the figure is 48 square inches.
How to calculate the surface area of a figureThe surface area is equal to the sum of all the areas of the sides of the figure.
The figure shown consists of 6 parallelograms. The area for calculating the area of a parallelogram is expressed as:
Area = Base * Height
Surface area = 4(2*4) + (4 * 4)
Surface area = 4(8) + 16
Surface ares = 48 square in
Hence the surface area of the prism is 48 square inches.

What percent of children who have a birthday party at home are between 5
and 10?
The percentage of children who have a birthday party at home between 5
and 10 is 3.69 %
What is a percentage?The percentage means the required value out of 100.
It is calculated by dividing the required value by the total value and multiplying by 100.
The percentage change is also calculated using the same method.
In percentage change we find the difference between the values given.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
We have,
Total number of children = 325
The number of children that have parties at home between the 5 - 10 age group.
= 12
Now,
The percentage of children who have a birthday party at home between 5
and 10.
= 12/325 x 100
= 3.69 %
Thus,
The percentage of children who have a birthday party at home between 5
and 10 is 3.69 %

The graph shows the population of a city n months after the establishment of a new automobile plant in the city.
Answer: for sure the answer is increased rapidly
Step-by-step explanation:
The population of the city increased rapidly for the first four months and then slowly approached 7000 people.
What is Graph?A graph contains data of which input maps to which output.
Analysis of this leads to the relations which were used to make it.
If we know that the function crosses x axis at some point, then for some polynomial functions, we have those as roots of the polynomial.
WE have given the graph shows the population of a city n months after the establishment of a new automobile plant in the city.
We can see that at 4000 people, the graph increases and then become constant at the rate of 7000 people.
So we can conclude that the population of the city increases rapidly for the first four months and then slowly approached 7000 people.

I have 35 quarters and dimes in
my pocket. How many of each do I have if I have $5.45??
HELP Me pls
Answer:
13 Quarters, 22 Dimes
Step-by-step explanation:
.10d + .25q = 5.45
.10 (35 - q) + .25q = 5.45
3.5 - 10q + .25q = 5.45
.25q - .10q = 5.45 - 3.5
.15q = 1.95
q = 13
Plug the value of q to solve for d, or the number of dimes.
d = 35 - q
d = 35 - 13
d = 22
A seamstress needs to cut 15-inch pieces of ribbon from a roll of ribbon that is 9 feet in length. What is the greatest number of 15-inch pieces the seamstress can cut from 5 of these rolls of ribbon
Answer:
35 strips :)
Step-by-step explanation:
1 foot; 12 inches
Now lets solve!!
12 x 9 = 108
Now we must divide :)
108/15 = 7
Since she has 5 rolls, we need to multiply 1 more time :)
7 x 5 = 35
Have an amazing day!!
Please rate and mark brainliest!!
Answer:
35
Step-by-step explanation:
1 foot = 12 inches
so (multiply both by 9)
9 feet = 108 inches
108 divided by 15 = 7.2
the .2 part can't be used, so each roll can make 7 pieces of ribbon
Theres 5 rolls of ribbon so multiply 7 by 5 which is 35
