Answer 1

The answer is B

Explanation:

If you earn $5 when you mow the lawn, you now have $5 in your wallet. You then go and spend $5 on candy, which means you now have $0.

Answer 2

A. 20 - 10 = 10 (you will still money left)
B. 5 - 5 = 0
C. 10 - 2 = 8 (you will still money left)
D. 10 + 5 = 15 (you will still money left)


Therefore, our final answer is B



Hope this helps!
