Answer 1

A) Ben lost ten pounds and then gained 10 pounds.

Explanation:

Bill lost ten pounds and then gained ten pounds. +10 and -10 are opposites and combine to make 0.

Answer 2

A, because of Bill lost ten pounds, but he gained them back, nothing has happened. The situation is still the same. He still weights what he started out as, no more, no less. However, if a business makes 10 but they bought what they are selling for 20 for example, this is a situation where it would not equal 0 (B).
