Minimum score to be considered = 105 - 20 = 85

Maximum score to be considered = 105 + 20 = 125

If p represents the performance of a student, then this inequality will be represented as follows:

                    85 ≤ p ≤125    

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.
