Question

A plumber charges of fee of $75 to make a house call. He also charges $50 per hour for labor.

1. Write an equation that represents the plumber's charges. Let x represent the number of hours for labor an dy the total cost.
2. Use equations from part one to predict the cost of hiring the plumber for a 5-hour long repair.

Answer 1

For part 1- y=50x+75 For part 2- y=325

Explanation:

the cost is increasing 50 for every hour

there is a flat rate of 75 to answer a house call

y=50x+75

y=50(5)+75

y=250+75

y=325
