Ava needed to get her computer fixed. She took it to the repair store. The technician at the store worked on the computer for 3.5 hours and charged her $59 for parts. The total was $461.50. What was the cost of labor, per hour?
To find the cost of labor per hour, we need to subtract the cost of parts from the total cost and then divide that amount by the number of hours worked on the computer.
The cost of labor is $461.50 - $59 = $402.50.
The cost of labor per hour is $402.50 / 3.5 hours = $<<402.50/3.5= !115>>115 per hour. Answer: \boxed{115}.
