Ok here is a question. Three friends check into a hotel. The cost of the room is normally $30. They are suppose to get a discount on the room, but at the time of check in the lady at the desk does not know of the discount and charges them the full price. So each of the friends pays $10 to cover the cost of the room. Then later the front desk lady realizes the friends were right, and the cost of the room should have been only $25. So the lady gives a bellboy a $5 bill, and asks him to give it as a refund to the friends. On the way up to the room the bellboy decides that the $5 bill could not be divided up evenly by 3 people. He then takes the five and pockets it, but gives the friends back $1 each. Ok so here is the question, if the friends only paid $9 dollars each that equals $27. And the bellboy made $2, then the $27 + $2 only = $29. What happened to the other dollar?
