Question

A plumber charges a $55 house call fee and an additional $42 an hour. He fixes the pipes in your building and charges $265. Solve the following equation to determine h, the number of hours the plumber worked.

Answer 1

Explanation:

You haven't given the equation, but I can make one up.

Cost = 55 + 42*h

So let the cost = 265 dollars

265 = 55 + 42h Subtract 55 from both sides

210 = 42h Divide both sides by 42

210/42 = 42h/42

h = 5

He worked 5 hours.
