97¢

Step-by-step explanation:

If 4 liters cost $3.88, then divide 4 into 3.88

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.

then,

we have an inequality i.,e

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