Aplumber charges a service fee of $40 plus $25 per hour for labor. write a function rule for the total cost of hiring the plumber for a job that takes x hours. how much would it cost to hire the plumber for a job that takes 4 hours?

40+25x= total price   four hours=40+(25*4) or 140

Step-by-step explanation:

40 is original and 25 is per hour. so 40+25x(x stands for hours) and 40+25x if 4 is the variable it is 40+(25*4)

the answer is 1030 it's very simple math.
