Question

A plumber charges $70.00 for the first hour and $50.00 for each additional hour spent on a job. The plumber does not adjust the cost for partial hours, so a partial hour is charged as a full hour. The service charge in dollars, S, as a function of time in hours, h, is what type of function? A. exponential function B. step function C. linear function D. periodic function

Answer 1

The answer is C, a Linear Function.

Answer 2

Answer: linear function

Explanation:

I believe it's a linear function due to the fact you start with $70 and for every hour after, x, is $50 so there is no change in increase. So it is linear. Hope this helps!
