Question

You are participating in a school bake sale as a fundraiser for your basketball team. Your goal is to raise at least $150 by selling brownies and cookies. You are selling brownies for $2.50 each and cookies for $1.50 each. First, select an inequality to represent the number of brownies, b, and cookies, c, you would need to sell to meet your goal of raising $150. Then, select the possible number of brownies and cookies you could have sold to meet your goal.

Answer 1

2.5b + 1.5c ≥ 150

Example 100 brownies and 50 cookies

Explanation:

To write an expression, define the variables.

c is number of cookies

b is number of brownies

To find the total money they earned, write 2.5b + 1.5c which includes the cost of each brownie and cookie.

2.5b + 1.5c ≥ 150 so you have at least $150.

This means you could sell 100 brownies and 50 cookies and earn $325.
