One of the difficulties of engaging in global trade is the constant shift in exchange rates.

How much do exchange rates change over a 30-day period? Research this by choosing five currencies (say, the euro, the British pound, the Japanese yen, the Mexican peso, the Saudi Arabian riyal) and looking at their exchange rates relative to the U.S. dollar for the past month. The rates are available online at Yahoo! Finance (finance.yahoo.com/currencyconverter). Choose a company and describe what effects the currency shifts you noted might have on this company’s trade with each of the countries or areas whose currency you chose.
