In an article titled, Gas prices dropping after last week's spike, that was published in The Atlanta Journal-Constitution newspaper on August 29, 2011, Mike Morris wrote:

"After a spike last week as Hurricane Irene threatened East Coast oil refineries, Atlanta gas prices have started falling, according to a website that tracks how much we pay to fill up our tanks. Metro Atlanta's average price early Monday of $3.65 for a gallon of regular unleaded was a penny cheaper than on Sunday and 4 cents below the national average".

Please relate this paragraph to what you have learned in Chapter 4. What caused prices to rise and then to fall? Are there other products that may have experienced changes in prices as a result of Hurricane Irene? Why?

To help you figure this out, draw a Supply/Demand graph for gas for yourself (not to submit to me). If it's easy for you to scan your graph and attach it to your post, do that. But if it's not easy to do that, just describe your graph in words. That is, explain how you labeled the axes of your graph, what the demand curve looks like, what the supply curve looks like, how you labeled the equilibrium price and quantity, any curve shifts, and what happened to equilibrium price and quantity as a result of the curve shifts (changes in demand and/or supply). [You will have to be able to explain how to draw a supply/demand graph on the first exam.]
