Factor x3 – 4x2 + 7x – 28 by grouping. What is the resulting expression? (x2 – 4)(x + 7) (x2 + 4)(x – 7) (x2 – 7)(x + 4) (x2 + 7)(x – 4)

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.

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
