Question

Steve wants to buy sunglasses and he can spend at most $168. He has a coupon for $20 off any item at that store. Which inequality can he use to find the original price p of the sunglasses that he can buy?

p - 20 ≤ 168
p - 20 ≥ 168
p - 20 > 168
p - 20 < 168

Answer 1

a)

Explanation:

The price p minus the 20 dollars he can use a coupon for must not be more than the 168 dollars he has. Thus p-20 must be smaller than or equal to 168.

This is expressed as

`p-20\leq 168`
