Abe, a plumber, charges $50 per hour plus $75 for making an in-home visit. the plumbing service charges $65 per hour but no set fee for a visit. how many hours of pluming work are needed for each to cost the same?

5 hours.

Step-by-step explanation:

Let x be the number of hours.

Abe, a plumber, charges $50 per hour plus $75 for making an in-home visit.

Cost of Abe =       ....(1)

The Plumbing Service charges $65 per hour but no set fee for a visit.

Cost of Abe =         .... (2)

We need to find the hours of pluming work are needed for each to cost the same.

From (1) and (2) we get

Divide both sides by 15.

Therefore, 5 hours of pluming work are needed for each to cost the same.
