Math Challenge #2 "How many pennies?"

How many pennies? from John Flaten on Vimeo.

We will have until Wednesday, Nov. 7th, then the answer will be revealed. All guesses can come to my comments, or the inbox in my room on my desk. Again, anyone who sees this will be in the challenge and if I know you personally I'll get you a small prize. Enjoy and good luck.
