Julien, Anthony and Tanner go to check into a hotel. The hotel manager tells them there is only one room left, costing $30. They decide to share that room for $10 each person. Later, the manager realizes the room is only $25. He calls the bell boy and tells him to give the $5 back. The bell boy decides since you cannot divide $5 by three people, he’ll take $2 for himself and return $1 to each person. So each person paid $9 and the bell boy has $2. That is 9X3=27, plus the bell boy's $2 is $29. Where is the extra dollar?
