Question 1208083: 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. function. 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. 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.

comment from student: Why do you insist on arguing with me?
All math problems are copied and pasted here from my college algebra textbook.
I don't understand what your problem is, really.
My response : I do not argue with you, and I do not insist on arguing with you.
You posted your problem/question to the forum.
I replied showing my opinion about it. That's all.
I do not try to convert you to my faith.
You may believe in/to everything you want.
