it is not D because you have 1 dollar and 60 cents so it is 1.60
OpenStudy (anonymous):
but wouldn't that mean peggy has $1.60?
OpenStudy (ltrout):
Yes but they are saying that n is worth 5 cents, so it wouldn't be 1.60, because then 1 n would already be 5 > 1.60.
OpenStudy (ltrout):
160 cents is the same as $1.60
OpenStudy (anonymous):
but you would still have one dollar and sixty cent correct? so wouldnt it be 1.60?
