　　Mr. White was the owner of a hotel in the town. One weekend all of the hotels were full because a large meeting was being held in the town. On Saturday night, three men came into the hotel and asked for rooms. Mr. White explained(解释) that there were no rooms for them. The men didn't want to go because they had no place to stay.

　　Mr. White wanted to help them. He remembered that Room 418, a very small room, was empty. He asked them if they would share(分享) a room. The three men said that they would.

　　Mr. White told them that the room would be $10, and then they went up to their room.

　　Mr. White soon began to feel sorry.“Thirty dollars is too much for the small room.”He called his assistant over and said,“Here is $5. Give it to the men in Room 418. They paid too much for the room.”

　　The assistant took the money. While he was on his way to Room 418, he thought,“How can three men divide(分) $5? I'll give each of them only $1, and I'll keep $2. They'll be happy to get something back. I'll make a little money and Mr. White will never know.”So, he returned $1 to each man.

　　Each man had first paid $10. After the assistant gave $1 back to him, each one had actually (实际) paid only $9. $9×3=$27. The assistant kept $2. $27＋$2=$29. Where is the missing dollar?
