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?
