"For those of you who answered that the U.S. uses the dollar, the U.K. uses the pound and Japan uses the yen, you are correct," Antonio said. "There is also a Euro-Dollar, which is very important, and other countries use the dollar as currency as well, amongst them Canada and Australia. But, the value of the dollar in different countries is different, and that's what we are going to learn about next.

Before we do that, though, I would like to have you all work on converting wizarding money into the United States dollar. To start, I want to see if you can figure out $100.00 in United States money is equal to in wizarding world money. Everyone, go ahead and use your calculators to perform this exercise, please. We'll be using this calculator a bit more then move on to the other calculator, then the second part of the lesson."
