Question

A group of students are selling homemade oatmeal cookies at $3 dollars per bag. The students spent $23 on all the supplies to make the cookies. Which expression can be used to find the profit made from selling W bags of cookies after accounting for the amount they spent on supplies? Explain how you got your answer.

A. 3 x W - 23
B. 3 x W + 23
C. 3 - W + 23
D. 3 + W + 23

Answer 1

A. 3 x W - 23

Explanation:

Profit is equal to money made minus costs

Let P equal profit. We know the costs were 23, and they made 3 dollars per cookie. If they sold W bags of cookies, the money made is 3*W

P = 3*W - 23
