Question

Solve the problem.

Two plumbers make house calls. One charges $90 for a visit plus $45 per hour of work. The other charges $65
per visit plus $55 per hour of work. For how many hours of work do the two plumbers charge the same? Help!!

Answer 2

The total cost for plumber number 1 expressed as a function of x is
