Question

Clay hired an electrician to install a light fixture in his house. The electrician charges$58 per hour for labor plus a $50 service fee. If Clay's bill is $187, determine howmany hours of labor was charged?

Answer 1

2hours and 22 minutes (approximately)

1) Gathering data from the question.

$58 per hour + $50 service fee (fixed)

If Clay's bill is $187 How many hours?

2) We can write it as an equation, since the hours may vary but the service fee is fixed. So the bill was calculated by that equation below:

58h +50 = 187

Solving for h

58h +50 -50 =187 -50

58h =137 Dividing both sides by 58

h =137/58

h=2.36

This corresponds to 2 hours and (0.36*60)

2hours and 22 minutes (approximately)
