Riddle me a Riddle

Here is a riddle that my high school math teacher told us that boggled my mind for a while.

There were 3 business men who split the cost of a $30 hotel room. The manager realized that he had overcharged the 3 men by $5. So he gave the bell boy five dollars and told him to take it to the three men. On the way to the room the bell boy thought, mmmm, 5 dollars can't be split evenly among three men, so he pocketed $2 and returned to the men $3, or a dollar to each man. So each man thought he had payed $9 each instead of $10, for a total of $27. The bell boy kept $2 dollars, which added to the $27 that the men paid totals $29. Where is the missing dollar? ($30 was paid originally)

Sometimes there is no sound

So I can't figure out why the sound isn't carrying over from our camcorder to the downloaded video...so this is all there is for now. It's late and I didn't have time to put other sounds to these clips. Use your imagination.
