Answer
Attempt 1 out of 2
Equation:
Answer: xx =
Let the cost of the labor per hour be represented by xx.
The total cost is the sum of the cost of the labor and the cost of the parts:
Total cost = Labor cost + Parts cost
Given that the technician worked on the computer for 4.75 hours and charged $77 for parts, the equation can be expressed as:
$290.75 = 4.75x + $77
Solving for x:
$290.75 - $77 = 4.75x
$213.75 = 4.75x
x = $213.75 / 4.75
x = $45
Therefore, the cost of the labor per hour is $45.
