Question 1208121: An economy car rented in Florida from National Car Rental® on a weekly basis costs $95 per week. Extra days cost $24 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 C of renting an economy car as a function of the number x of days used, where 7 <= x <= 14. Graph this function.

An economy car rented in Florida from National Car Rental® on a weekly basis costs $95 per week.
Extra days cost $24 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 C of renting
an economy car as a function of the number x of days used, where 7 <= x <= 14. Graph this function.
~~~~~~~~~~~~~~~~~~~~~
The problem says that
"An economy car rented in Florida from National Car Rental® on a weekly basis costs $95 per week."
A week is 7 days; so this rate is 95/7 dollars per day.
But this fraction, 95/7 dollars, is neither an integer number of dollars nor an integer number of cents.
So, it is unclear to me how to treat this problem.
In my view, the problem is composed incorrectly (= by an illogical way).
To me, it is an example on how a Math problem SHOULD NOT be composed.
