Question

Dylan paid a plumber $120 for 4 hours of labor. How much does the plumber charge per hour of labor?
$15 per hour
$30 per hour
$116 per hour
$480 per hour

Answer 1

To find out how much the plumber charges per hour of labor, you can divide the total amount paid by the number of hours worked.

Dylan paid the plumber $120 for 4 hours of labor:

\[
\text{Charge per hour} = \frac{\text{Total Amount Paid}}{\text{Number of Hours}} = \frac{120}{4} = 30
\]

So, the plumber charges **$30 per hour**.
