what will be the cost for 8 hours of work? 10 hours of work?

A plumber charges $25 for a service call plus $50 per hour

Cost = 25 + 50h

Where h is the number of hours of service

8 hours of work: h = 8

Substitute with h = 8 at the equation of cost

Cost = 25 + 50* 8 = $425

10 hours of work: h = 10

Substitute with h = 10 at the equation of cost

Cost = 25 + 50 * 10  = $525
