Question

Chelsea is budgeting for her trip to the mall. She

does not want to spend any more than $140. If
she wants to buy a dress that costs $28.50 and
I some shirts that cost $20.75 each, how many
shirts can she buy? Use the inequality to help
solve the problem.
140 > 28.50 + 20.75x

Answer 1

Chelsea can buy 5 shirts.

Explanation:

1. Subtract 28.50 from 140. This is because subtraction is the inverse of addition, so it will cancel out. 111.50 > 20.75x
2. Divide both sides by 20.75. Division is the inverse of multiplication. 5.3734939759 > x

You can't split shirts when buying them, so Chelsea can buy 5 shirts.
