Question

Helpp

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

195 is the answer
336-141=195

Answer 2

Answer: x = 65

================================================

Work Shown:

x = cost of labor per hour

3x = cost of the 3 hours of labor

3x+141 = cost of labor plus parts = total cost

3x+141 = 336

3x = 336-141

3x = 195

x = 195/3

x = 65

The hourly wage is $65 per hour for labor.

------------

Check:

1 hour = 65 dollars in labor costs

3 hours = 3*65 = 195 dollars in labor costs

195+141 = 336 dollars total

The answer is confirmed.
