3 men go into a hotel. The man behind the desk says a room is $30 so each man pays $10 and goes to the room. A while later the man behind the desk realized the room was only $25 so he sent the bellboy to the 3 guys' room with $5. On the way the bellboy couldn't figure out how to split $5 evenly between 3 men, so he gave each man a $1 and kept the other $2 for himself. This means each man paid $9 for the room, which is a total of $27 add the $2 that the bellboy kept = $29. Where is the other dollar?
