Question

1. an electrician charges $40 to come to your house. she also charges $55 for each hour that she works. the electrician charges you a total of $190. how many hours does the electrician work at your house? use h for the number of hours.

Explanation:

Step1: Set up cost equation

$40 + 55h = 190$

Step2: Isolate the hourly term

$55h = 190 - 40$
$55h = 150$

Step3: Solve for h

$h = \frac{150}{55} = \frac{30}{11} \approx 2.73$

Answer:

The electrician works $\frac{30}{11}$ (or approximately 2.73) hours.
