Question

Jennie had minor service done on her car. The bill was $341.48 for parts
and labor. She was charged for 2.5 hours of labor, and the labor rate was
$121 per hour. How much were the parts? Since the end result (the total
bill) is provided, work backward from there to find the requested
information?

Answer 1

The equation shows that the amount for parts will be $38.98

How to illustrate the equation?

Amount of bill = $341.48

Let amount of parts be x.

She was charged for 2.5 hours of labor, and the labor rate was $121 per hour. Therefore, the amount here will be:

= $121 × 2.5

= $302.50

Therefore, the amount for parts will be:

= $341.48 - $302.50.

= $38.98
