Three girls paid \$100 each, a total of \$300, to share a Motel Room. Later, the desk clerk realizing she should have only charged \$250, gives the Room Attendant \$50 and asks him to return it to the three girls. Unable to divide the money three ways, he decides to give \$10 to each girl and pockets the remaining \$20. The girls have now paid \$90 each or \$270 for the room, and the room attendant has \$20. What happened to the other \$10?
