Question

Mr. Harris has some money in his wallet. He pays the babysitter $12 an hour for 4 hours of babysitting. His wife gives him $10, and he puts the money in his wallet. By how much does the amount in his wallet change?

Answer 1

-38.

Explanation:

Answer 2

12 x 4 = 48 but in this case we are taking away the money so -48. Then, his wife gives him 10 so we have 10 + (-48) which equals -38.

The amount in his wallet changed by -38.
