Question 6

A plumber charges a base fee for all service appointments. If a repair is needed, he adds a charge for each hour of labor. If the total cost, y, in dollars, of the plumber's x-hour repair visit is modeled by
the equation y = 25x + 30, what could the 30 represent?

Answer 2

It represents the base fee

Explanation:

Well we know he charges a flat rate for even making an appointment (probably because he needs to get to a client), and then charges an hourly rate. Thus, anything in his formula that's multiplied by the number of hours must be the hourly rate (25 here) and whatever is constant must be the base fee (30 here).
