Question

A rental company purchases a truck for $14,500. The truck requires an average cost of $6.75 per day in maintenance.
(a) Find a linear function that expresses the total cost C of owning the truck after t days.
C(t) =

(b) The truck rents for $55.00 a day. Find a linear function that expresses the revenue R when the truck has been rented for t days.
R(t) =

(c) The profit after t days, P(t), is given by the function P(t) = R(t) − C(t). Find the linear function P(t).
P(t) =
