FOREIGN EXCHANGE RATESTHE YEN FOR DOLLARS. The Federal Reserve System Web site, www.federalreserve.gov/releases/H10/hist, provides historical foreign exchange-rate data for a wide variety of currencies. Look at the data for the Japanese yen from 2005 to the present. Assume that you were in Tokyo every New Year's from January 2 or 3, 2005, to this year and bought sushi and sashimi for 5000 yen each year. Convert this amount to dollars using the yen-dollar exchange rate for each January since 2005, and plot the dollar price of the dinner over time. Has the dollar appreciated or depreciated against the yen? What was the least amount in dollars that your box lunch cost? The most?
