Mr. Jensen owed $34.75 on his Internet service. He accidentally paid $37.45. When his next statement came, it showed a balance of –$2.70. Which statement about this bill is true?

Mr. Jensen paid $37.45 but owed only $34.75, so he paid $37.45 − $34.75 = $2.70 too much. The −$2.70 balance means he has a $2.70 credit, which will reduce the amount he needs to pay on his next bill. Therefore, he needs to pay $2.70 less.
