You work for a US-based international mustard company and are considering opening some branches overseas to sell. Obviously, overseas mustard sales will be in the respective country's currency, but you want the profits to come back to the US to distribute to your shareholders. Your prospective countries to open are Japan, Egypt, Mexico, and New Zealand. 

Look back over the past three months of exchange rate data on Yahoo Finance and describe how wise it would be to open a branch in each of the countries. Be sure to support your answers. Be sure also to compare similar graphs; i.e. USDJPY, USDEGP, USDMXN, and USDNZD, which will all give you the amount of foreign currency trading for one dollar.
