Hi,
So the question goes as follow:
An item costs x dollars where x is a positive integer.
Quantity A:
The price of the item after a 10% discount and then a $10 off coupon are applied
Quantity B:
The price of the item after a $10 off coupon and then 10% discount are applied
I understand that if you choose special numbers the answer seems to come out to be B every time. However, one thing that is not specified is that the original amount should be more than 10 dollars. If the amounts we pick to test this is 5, for example, than we end up in both situations having nothing left after the 10 dollar discount which would then make both columns equal and subsequently make the answer D since in some instances the answer is B and in others (where the original amount is less than 10) the answer is C.
Am I missing something here?
