Question

During the winter, you charge people $12 for going to their house to shovel, then $9 every hour you shovel. If you make $57 one day, how many hours did you spend shoveling? (solve the equation)

Answer 1

Your answer is 6 hours that day.

Answer 2

The number of hours you spent shoveling is equal to 5 hours.

• Let the service charge be F.

• Let the cost of shoveling per hour be C.

• Let total earnings be T.

Given the following data:

• Cost of shoveling = $12

• Cost of shoveling per hour = $9

• Total earnings = $57

To determine the number of hours you spent shoveling:

First of all, we would determine the cost of shoveling for this particular by subtracting your service charge from your total earnings.

$Balance = T-S\\\\Balance=57-12$

Balance = $45

Now, we can calculate the number of hours you spent shoveling:

$Time = \frac{Balance}{C} \\\\Time = \frac{45}{9}$

Time = 5 hours
