It only took them an hour and they lied about it.

The bill for repairing a car was \$345.

The cost for parts was \$160.

The cost for labor which was \$37 per hour was \$185.

The repair took 5 hours.

Take \$345 and subtract \$160.

It equals \$185.

Now take 185 and divide by 37.

It equals 5.

I want to know where car repair shops are charging \$37 per hour for labor?

Most shops in my area charge over \$100/hour

Labor cost=\$345-\$160=\$185

185/37=

Let's let H = number of hours spent repairing

Total cost = 345

cost of parts = 160, this does not change (by hour or anything else)

cost of labor = 37 per hour times the number of hours = 37 * H

Total cost = cost of parts + cost of labor

345 = 160 + 37 * H

I leave it to you to finish

Unrealistic math problem. No one charges 37 an hour for labor
