Melinda had $45 when she went to the mall. She spent $9 on a pair of sunglasses. Then she wants to buy some shirts that are on sale for $12 each. Write and solve an inequality to represents the number of shirts can buy
First set up the inequality. 12x + 9 <= 45 subtract 9 from both sides 12x + 9 - 9 <= 45 - 9 12 x <= 36 divide both sides by 12 x < = 3 She can buy at most 3 shirts
