I tried this once before, you have three hunters staying at a hotel that cost thirty dollars a night. So the three hunters each take ten dollars and give it to the lady at the cash register. She hands them a key and they go off to there room. She finds out later that she madea mistake and the room cost twenty five dollars. So she hands fiveONE dollar bills to the bell hop and he walks tothe huntersroom. He takes two dollars and puts it in his pocket for a tip and hands three one dollar bills to the hunters. So they got a dollar back out of their original ten making the room nine dollars. So 3x9 is 27 plus the 2 dollars the bell hop but in his pocket makes 29. Where is the extra dollar? Sorry if you have done this before and I wasted your time.
