1) very good, it the 100 bucks is real, your answer is correct, but it is fake, so your answer is wrong
  @  E* B* y# @9 p公仔箱論壇
& g( T+ z3 I" X; Y& A, _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.tvb now,tvbnow,bttvb/ x3 H. `1 j) ~
