3 men rent hotel, clerk tells them $30. they each pay $10.
the clerk then notices the room is only $25
gives the bell boy 5 1's to return to the men
he thinks on the way up ill keep $2 and give them $3
he gives them $3 so now they each paid $9
$9 x 3 = $27 if the bell boy only kept 2 and was givin $5 what happened to the other $1???

should be simple but its throwing me for a loop
