tell us about a price that has recently changed and tell us why. Provide a link to a news article about the good or service you chose. Remember, news articles don't always get the economics right; you article doesn't need to grounded in solid economic theory, it's simply a link to information on a price change in the real world. You are the one who will explain the economics to us in your post. Use what we learned in this chapter -- that the price is the result of the interactions of supply and demand -- use supply and demand to explain why the price is what it is and what causes it to be so
