Question 1113995: A plumber charges $80 for a service call plus $30 per hour.
a. Find a linear function that represents the total daily charges C, in dollars, as a function of the time t, in hours, spent at a given location.
b. If the total charge was $140, how many hours did he work?
You can put this solution on YOUR website! 80 + 30t = total charge
-------------------------------------
80 + 30t = 140
30t = 60
t = 60/30 = your answer
