Question

An Electrician charges $30 for a service call plus $75 per hour of service. If he charged 210 how many hours did he work?

Answer 1

Answer:

2.4 hours Electrician works.

Step-by-step explanation:

Let us assume that the number of hours  Electrician works be x.

As given

An Electrician charges $30 for a service call plus $75 per hour of service.

If Electrician  charged $210.

Than the equation becomes

30 + 75x = 210

75x = 210 - 30

75x = 180

$x =\frac{180}{75}$

x =2.4 hours

Therefore 2.4 hours Electrician works.
