Answer 1

Answer: $105 an hour

Explanation:

Answer 2

Here it is given that x is the cost of the labor per hour.

Now the technician at the store worked on the computer for 4 hours

Total labour charge = $ 4x

The technician charged her $ 77 for parts

So the required equation is

4x + 77 = 497

We now solve for x as below

4x + 77 = 497

⇒ 4x = 420

⇒ x = 105

The cost of the labor per hour = $ 105
