An electrician charges $75 as a one-time fee plus an additional $45 per hour. If the total bill is $131.25, how many hours did it take for the electrician to complete the repair? Define the variable for this problem.
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}.
Define the variable for this problem.
Let x be the number of hours the electrician took to complete the repair.
Write an equation with the variable to represent the situation.
The equation that represents the situation is: $45x + $75 = $131.25.
Solve the equation. Show ALL work.
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.
is this 100% percent correct
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.
