think about it, when the bill is fake, and he gave him $79 change back, that is -79 already, it means the 100 on his hand is equal to 0 (Zero), how did he makes profit when he got a fake bills, then he need to pay another real 100 dollars bill to his neighbor, that another -100, plus the product he lost, thats another 18 dollars, Do Not Even Mention the 3 dollars, there is no profit he can make when he got a fake bill.. }3 D0 y% O& c& Z$ a& Q5 U

dun forget that guy, not only the $18 dollars product he got on hand, he also got $79 dollars on this hand, he paid a fake 100 dollars bill, it means he paid nothing, and the boss gets nothing too, so u need to add 79 dollars to the total.
