Yes, your answer is correct, but is only the 1st part, u forgot he paid back another $100 to his neighbor, that is another $100, not related to the first $100, you really have to 想清楚

think 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.5 I7 c: |- Q6 B; D8 t
