Question

A service charges a flat setup fee of $40 plus $12 per hour. (a) Write a linear function that represents the total cost C (in dollars) as a function of hours h. (b) Identify the slope and y-intercept and explain what each means in context. (c) Create an input-output table for h = 0, 1, 2, 3, 4, and 5 hours. (d) Graph the function on a coordinate plane with an appropriate scale. (e) Use the graph to estimate the total cost for 3.5 hours of service.
