During the fall, you decide to rake leaves and charge $12 for coming to a house and raking, and then $9 for every hour you rake. If you make $57 in each of 3 houses you went to in one day, how many hours did you spend shoveling?

Answer:

15

Step-by-step explanation:

For 1 house, the charge just to go to a house is $12.

In each house you made $57.

$57 - $12 = $45

The charge per house just for raking was $45.

You charge $9/hour.

$45/($9/hr) = 5 hours

You shoveled 5 hours in each house.

3 * 5 hours = 15 hours

Answer: 15 hours
