(7.RP.3) (4 pts)(1 point) A. How many laptops will the school have in total this year? Question 2 (1 point) B. If the cost of each laptop is $800, what will be the total cost for the laptops

Answer 1

A. To calculate the number of laptops the school will have this year after increasing the number by 15%, we can use the formula:

\[
\text{New laptops} = \text{Old laptops} \times (1 + \text{Percentage increase})
\]

In this case, the old number of laptops is 200, and the percentage increase is 15% (or 0.15).

\[
\text{New laptops} = 200 \times (1 + 0.15) = 200 \times 1.15 = 230
\]

So, the school will have **230 laptops** in total this year.

B. To find the total cost for the laptops, we multiply the number of laptops by the cost per laptop:

\[
\text{Total cost} = \text{Number of laptops} \times \text{Cost per laptop}
\]

Given the number of laptops is 230 and the cost of each laptop is $800:

\[
\text{Total cost} = 230 \times 800 = 184,000
\]

Thus, the total cost for the laptops will be **$184,000**.
