What happened to the other dollar?
Three men walk into a hotel, and they tell the desk clerk that they want accommodations for the night. He tells them that it will cost them $10 each, collects the money from each of them, and instructs the bell boy to show them upstairs to the rooms.
Once upstairs, the bell boy discovers that, being good friends, they don't want three separate rooms, but one room with three beds, so he goes down to tell the desk clerk.
The desk clerk informs the bell boy that one room for three people is less than three room for one person ~ the one room only costs $25. Then he gives the bell boy the key to the new room and $5 change to give the men.
On the way upstairs, the bell boy thinks to himself, "There are three men, and five dollars. I can't divide it equally among them"! So he thinks of a scheme...
He takes the men to the new room, gives them each $1, and keeps the extra $2 for himself.
---------------------
Now, if each of the men originally paid $10, and they each got $1 back, then they each paid $9.
$9 times 3 is 27... so they paid a total of $27. plus the two the bell boy kept makes $29.
