Car Rental Costs An economy car rented in Florida from Enterprise® on a weekly basis costs per week. Extra days cost per day until the day rate exceeds the weekly rate, in which case the weekly rate applies. Also, any part of a day used counts as a full day. Find the cost of renting an economy car as a function of the number of days used, where . Graph this function.

To find:
a. The cost of renting an economy car as a function of number of days used, where .
Answer to Problem 54AYU
Solution:
a.
Explanation of Solution
Given:
IIt is given that an economy car rented in Florida from Enterprise on a weekly basis costs per week.
Extra days cost per day until the day rate exceeds the weekly rate, in which case the weekly rate applies.
Part of a day used counts as a full day.
In a week, from 5th day the cost becomes weekly basis as 5th day itself cost 185.
