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
