A. Solve using a spreadsheet program such as Excel. Indicate the spreadsheet formula showing numeric values rather than cell references. For example, for the value that $ 100 today could grow to in two years, assuming 10 percent annual compounding, the spreadsheet solution formula would be: FV(10%, 2, 0, 100).
