Question

A plumber charged x dollars per hour for a 4-hour job plus $175 for parts. The to- tal charge for the service call was $415.00. Which equation can be used to deter- mine how much the plumber charged per hour? ​

Answer 1

4x + 175 = 415

Explanation:

4 is the hours, so it should be multiplied by x to see how much you get every hour (and a total of 4 hours).

175 is the constant and should be added to the equation so that all fees are included.

415 is the total amount so the equation should equal that number.

Hope this helps!
