    Cool 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.
