Question

The Cost to repair a computer was $230. This included $155 for parts and $25 per hour for labor. How many hours of labor we are required to fix the computer?

Answer 1

Let x = number of hours required to fix the computer

$230 = $25x + $155

To solve for x, subtract $155 from both sides.

$75 = $25x

Divide each side by $25

3 = x

It took 3 hours to fix the computer
