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?

There is no other \$10. The total was \$300, the girls got back \$10 each, meaning they paid \$270 for the room, and the other guy took the last \$20, will adds up to the entire \$50 refund. The original \$300 is all accounted for. \$250 is in the cash register. \$30 is with the 3 girls, and \$20 is with the clerk.
