Think about it this way
( U: O9 k) u6 m. C: o0 z  n- ?1) if the 100 bucks is not a fake one, the store owner will gain $3 ($21-$18)% b: J( x+ x( y/ V  G  d9 |' O
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
