Three men went to motel to get a room. The clerk told them that the price of the room was $30. Each man gave the clerk $10 to pay for the room. Later the clerk realized he had overcharged the men and gave the bellhop $5 to give back to the men. The bellhop decided that $5 was too hard to divide equally among the three men so he gave each man $1 and kept the other $2. Each man originally paid $10 and got $1 back so they paid $9 each. Three times $9 is $27 and the bellhop kept $2.

Where did the other dollar go?
