Need A & B

You want to compare two separate retirement savings scenarios: (A) and (B). In scenario (A) you start immediately, contribute for a few years, but then stop contributing. However, you leave the accumulated savings to compound until retirement. In scenario (B) you start later (after the end of savings in scenario A) and contribute all the way to retirement. Calculate the accumulated amount of savings at retirement for the two scenarios. Scenario Annual Payment Payment Period Total Number of Payments Length of Investment Interest Rate (A) $8.000 End of years 1 to 9 9 27 years 10% (B) $8,000 End of years 10 to 27 18 27 years 10%
