Jocelyn needed to get her computer fixed. She took it to the repair store. The technician at the store worked on the computer for 4.75 hours and charged her $77 for parts. The total was $290.75. Write and solve an equation which can be used to determine xx, the cost of the labor per hour.

GPT-5 mini · Answer

Let x = cost of labor per hour. Then

4.75x + 77 = 290.75.

Subtract 77: 4.75x = 213.75.

Divide by 4.75: x = 213.75 / 4.75 = 45.

So the labor cost is $45 per hour.
