How much money would you have had to invest on 1/1/2010 in a savings bond that yields 4% interest (compounded quarterly) to have $100 on 1/1/2011?

Note that there are four quarterly periods at 1%. You can solve this with Excel, the PV table, or the formulas. The easiest way to show the calculation is PV = 100 / [(1.01) x (1.01) x (1.01) x (1.01)] = 96.10.
