Think about it this way
( O9 e9 C9 w% y! N/ \tvboxnow.com1) if the 100 bucks is not a fake one, the store owner will gain $3 ($21-$18)tvboxnow.com0 R2 c0 K6 E2 M8 S; q6 @
2) Now, the owner discovered that the 100 bucks is fake. You can think this as a lost of $100. therefore the overall gain is $3-$100 = -$97
