3 friends equally pay a hotel 27 dollars for a room. The hotel realizes the room was only 22 dollars. So, the owner tells the bell boy to give them the five dollars back. So, the bell boy brings the money and keeps 2 to make it easier. So each of the friends played 8 dollars. 8x3=24 plus the money the bellboy kept which is 2. That is only 26. Where is the missing dollar?
