Asked by Dom

Apex Plumbing charges a trip fee of $55 plus $15 for each quarter hour of service. John wrote an equation using, t , the total cost of a service call, as a function of, h , the number of hours the call lasted. What is the value of the slope in his equation and what does it represent?

dI hope John wrote

t = 60h + 55

the slope is 60 and it represents the hourly rate of $60
($15 per quarter hour = $60/hr)
