Step-by-step explanation:

11

step-by-step explanation:

32.50-7.50=25

225/25=11

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.
