3 guys walk into a hotel and request a room. (Don't ask why 3 guys are getting a room) The bell boy at the service desk says its $30, so each guy pays $10. As the bell boy at the service desk is putting away the 3 $10 bills, the hotel manager returns, see's this and says "The room is not $30, its $25, on sale this week. Go return $5."
As the bell boy is going up the elevator, he's wondering how he is going to split $5 between 3 boys - so he reasons "since I'm such a good guy, I'll give each guy $1 (3 x $1 = $3) and I'll keep $2 myself. Now, each guy renting the room has paid $9, and the bell boy keeps $2: $2 + (3 x $9) = $29 Where did the missing $1 go?
