Question

Jonathan needed to get his computer fixed. He took it to the repair store. The

technician at the store worked on the computer for 3 hours and charged him
$141 for parts. The total was $336. Write and solve an equation which can be
used to determine x, the cost of the labor per hour.

Answer 1

`141 + 3x = 336`

`3x = 195`

`x = 65`

So the cost of labor is $65 per hour.
