Answer: xx =

1 answer

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.
