There are three guys who go to a motel. They ask for a room, and the owner of the motel receives to them $30. After, when the three guys are at the room, the owner remember that room is only $25, so, he calls to the bellboy and say: "Give that $5 to the three guys". But tomorrow is his girlfriend's birthday, so the bellboy take $2 and only gives $3 to the three guys.(adsbygoogle = window.adsbygoogle || []).push({});

In the beginnig, each one had paid $10, but the bellboy has give them $1 to each one, so, they have paid $9 each one, and the bellboy has the $2, so...$9 + $9 + $9 + $2 = $29

So, what's happend with that last dollar?

(it is a stupidity, I know it)
