Use the distributive property to remove the parentheses.
7(x-5)

The answer is 7x-35

You multiply 7 by 5, then you remove the parenthesis, and rewrite the problem.

they will manufacture 8496 cars

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
