A plumber charges $45 an hour if the plumber charged Luke a $180.How many hours did she work

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 for 4 hours.
