    You have $80. Jeans cost $29 and shirts cost $12. Mom told you to buy one pair of jeans and use the rest of the money to buy shirts. Find the inequality.

    Let j be the number of jeans. Let s be the number of shirts. We are given:
    • Mom told you to buy one pair of jeans. So we have $80 to start with - $29 for 1 pair of jeans = $51 left over
    Now, since shirts cost $12 each, and our total number of shirts we can buy is s, our inequality is 12s <= 51.

    We want to find the s that makes this inequality true.

    Run this statement through our calculator, and we get s <= 4.25. But, we need s to be an integer, so we have s <= 4.
