Question

Ronnie charged his customers a flat fee of $25 to

fix computers. Then he charged $20 for each hour
that he spent fixing the computer. If Ronnie made
$175 off of his first customer, how many hours did
he spend working?

Answer 1

• 7.5 hours

Explanation:

Let the number of hours is x, then the following equation reflects the full charge:

• 25 + 20x = 175

Solve it for x:

• 20x = 175 - 25
• 20x = 150
• x = 150/20
• x = 7.5

Ronnie spent 7.5 hours.
