3 men went to a hotel to rent a room, the cost of the room was $30. Each man paid $10 to the bellboy and proceeded to there room. After a little while the
bellboy realized that there was a special on rooms that night and the price for the mens room should have been $25. On his way to the mens room to give them back $5 he was puzzled how he was going to split $5 as he had no change. He decided he would give them each $1 and keep the remaining $2 for himself. So each man originally paid $10, but after the bellboy gave each man $1 back, each man paid $9. 9 x 3 = $27 plus the $2 the bellboy put in his pocket equals $29. The original price for the room was $30. Where did the last dollar go?
