Part 1: Select ten foreign currencies and find the current exchange rate. Since currency exchange rates change often, you will need to look up the exchange rates. You can call a bank or look for foreign currency exchange rates on the Internet or in a newspaper. Part 2: Create a spreadsheet that lists the ten currencies you chose. For each currency, enter an amount and create a formula to convert it to U. S. dollars. Make sure to include dollar signs in the appropriate cells.
