1) very good, it the 100 bucks is real, your answer is correct, but it is fake, so your answer is wrong
$ ~' @8 g, ~$ s6 a5 j
& o5 J! K* l. h5.39.217.77:8898think about it, when the bill is fake, and he gave him $79 change back, that is -79 already, it means the 100 on his hand is equal to 0 (Zero), how did he makes profit when he got a fake bills, then he need to pay another real 100 dollars bill to his neighbor, that another -100, plus the product he lost, thats another 18 dollars, Do Not Even Mention the 3 dollars, there is no profit he can make when he got a fake bill.
