Question

Laura’s profit at a bake sale is represented by the function p = 5b - 15, where p is the profit, and b is the number of brownies she sells. Nicole’s profit is shown in the table. How much will each girl make if she sells 6 brownies?

Answer 1

$15

Explanation:

Given that the function for Laura's profit is

p = 5b - 15

where b= number of brownies

Given that she sold 6 brownies, we can estimate the profit.

to do this lets put b=6 in the expression for the profit we have

p = 5(6) - 15

p=30-15

p=15

Her profit will be $15
