Question 109703This question is from textbook College Algebra
: A rental company purchases a truck for $19,500. The truck requires an average cost of $6.75 per day in the maintenance.
(a)Find a linear function that expresses the total cost C of owning the truck after t days.
(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.
(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)
(d)Use the function P(t) that you obtained in 'c', to determine how many days it will take the company to break even on the purchase of the truck. Assume that the truck is in use everyday.This question is from textbook College Algebra
