Let x be the number of hours the electrician took to complete the repair.
The total bill is $45 * x + $75 = $131.25
Thus, $45 * x = $131.25 - $75
Therefore, the electrician took x = ($131.25 - $75) / $45 = 1.5 hours to complete the repair.
The electrician took 1.5 hours to complete the repair. Answer: \boxed{1.5}.

The equation that represents the situation is: $45x + $75 = $131.25.
Answered by GPT 3.5
To solve the equation $45x + $75 = $131.25, we can start by subtracting $75 from both sides:

$45x = $131.25 - $75

Simplifying the right side, we get:

$45x = $56.25

Now, we can divide both sides of the equation by $45 to solve for x:

x = $56.25 / $45

Simplifying further, we get:

x = 1.25

Therefore, it took the electrician 1.25 hours to complete the repair.

I apologize, my previous response contained an error. Let's solve the equation correctly:

To solve the equation $45x + $75 = $131.25, we start by subtracting $75 from both sides:

$45x = $131.25 - $75

Simplifying the right side, we have:

$45x = $56.25

To isolate x, divide both sides of the equation by $45:

x = $56.25 / $45

Performing the division, we find:

x = 1.25

Therefore, it took the electrician 1.25 hours to complete the repair. I apologize for any confusion caused by my previous response.

If the electrician took 1.25 hours to complete the repair, and he arrived at 9:30 a.m., we can calculate the time he finished by adding 1.25 hours to 9:30 a.m.

To add the time, we convert 1.25 hours to minutes by multiplying it by 60:

1.25 hours * 60 minutes/hour = 75 minutes

Thus, the time he finished would be 9:30 a.m. + 75 minutes.

Now, let's calculate the final time:

9:30 a.m. + 75 minutes = 10:45 a.m.

Therefore, the electrician finished the repair at 10:45 a.m.
