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

Answered by maham237 @



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.
