Answer 1

To find out how many hours the plumber worked, you can divide the total charge by the hourly rate.

The plumber charged Luke $180 and the hourly rate is $45 per hour:

$$\text{Hours worked}=\frac{\text{Total charge}}{\text{Hourly rate}}=\frac{180}{45}=4$$

So, the plumber worked 4 hours.

The correct response is 4 hours.
