3 guys go to a hotel and decide to share a room. The desk clerk charges $30. After each pays $10 and go to their room, the desk clerk discovers he overcharged $5 as the room was $25. He gives the bell boy $5 to give to the three but seeing that he couldn't split it evenly, he kept $2 and gave each $1. So............how much did each of the 3 pay for the room? If they gave $10 and got $1 back that is $9. $9 X 3 = $27 and the bell boy kept $2 for a total of $29 where did the other dollar go?
