3 men walk into a hotel to rent a room for the night, the lady at the front desk charges them 30 dollars, so each man pays 10 dollars each. afterwards she realized she over charged them by 5 dollars and gave 5 dollars to the bell boy to run up to them. on the way up the bell boy thought about it and figured that the 3 guys cant split 5 bucks to easy so he pocked 2 and gave them 1 dollar each. so the 3 men actually payed 9 dollars each and the bell boy kept 2.
WHERE IS THE MISSING DOLLAR?!
