Equation:
Answer:
Steps to solve:

Answer 1

$20

Explanation:

Say the amount of money spend is x and he uses up half of it. That would mean he has x/2. Then his parents let him wash the car for $7. Finally, you would end up with (x/2)+7 = 17

After you have the equation reverse it (sorry I cant word it any better) you would subtract 7 from 17 to get 10. Then multiply by 2 to get 20.

So the answer would be $20
