Where did the dollar go?
This isn't really homework, but something for you to think about...

Three men went to a hotel and rented a room for the night. it was \$30 for the room for one night. So each man payed \$10, totalling the \$30.

Later that evening, the receptionist realized that he had over charged them, and that the room was only \$25. He gave \$5 to the bellboy to give the men.

The bellboy didn't know how he would give the three men equal amounts, so he gave them \$3 and kept the \$2 for himself.

This meant that the three men payed \$9 each (3x9=27) and the bellboy has \$2, (27+2=29) only totalling \$29. Where's the other dollar?

This is the missing dollar problem.

This is a golden oldie.

There is no missing dollar. Men have now payed \$27, \$25 for the bill and \$2 to the bellboy. The other \$3 are in the pockets of the men

Glaysher is right. If you subtract rather than add the \$2 you get \$25, the price of the room.
