Electrician service call

Asked by maham237 @ in Mathematics viewed by 253 People

An electrician charges a service call fee of $60 plus $55 per hour. Another electrician charges a service call fee of $20 plus $65 per hour. Set up and solve an equation to determine the number of hours, h, for which the cost would be the same for hiring both electricians.

Answer:

Step-by-step explanation:

Electrician A:

60+ 55h

You will pay the electrician $60 no matter what plus an additional $55 per hour, h

Electrician B:

20+ 65h

You will pay the electrician $20 no matter what and $65 per hour, h

Put the equations together in order to solve for h:

60+55h= 20+ 65h

40= 10h

h= 4

If you hire either electrician for four hours, you will pay the same amount, which is $280
