3 men go into a motel.
the man behind the desk said the room rent is $30, so each man paid $10 and went 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 meant that the 3 men each paid $9 for the room,which is a total of $ 27,
add the $2 to that the bellboy kept = $29.

where is the other dollar?
