To determine the total hours \( h \) the plumber took to repair the leak, we can start by formulating the equation based on the charges.
The total bill consists of two parts:
1. A fixed charge for the visit: $65
2. An hourly charge: $75 per hour for \( h \) hours.
The total bill can be represented by the equation:
\[
65 + 75h = 196.25
\]
Now, we can solve for \( h \):
1. Subtract 65 from both sides:
\[
75h = 196.25 - 65
\]
\[
75h = 131.25
\]
2. Divide both sides by 75:
\[
h = \frac{131.25}{75}
\]
\[
h = 1.75
\]
So, the plumber took \( 1.75 \) hours to repair the leak.
To find the time he finished the repair:
- He arrived at 9:30 p.m.
- \( 1.75 \) hours is equivalent to 1 hour and 45 minutes.
- Adding this to 9:30 p.m.:
Starting with 9:30 p.m.:
1 hour later: 10:30 p.m.
45 minutes later: 11:15 p.m.
Thus, the plumber finished the repair at **11:15 p.m.**
