Question

Carmine paid an electrician x dollars per hour for a 5-hour job plus $70 for parts. The total charge was $320.

Which equation can be used to determine how much the electrician charged per hour?
5x = 320 + 70
5x = 320 - 70
(70+5)x = 320
O (70 - 5)x = 320

Answer 1

50$ an hour

Explanation:

this is correct because subtract the $70 for parts and you get 250 and divide that by the 5 hours she had worked, hope this helped
