Assume a 6% interest rate and annual compounding in the following two scenarios:

1) Assume Ace put aside $10,000 a year for 4 years, making payments at the end of each of those four years. Ace then just let the money accumulate interest for 6 more years. How much money would ace have after the 10-year period?

2) What would the amount be in 10-years if Ace saved for the first 4 years by making payments at the beginning of each of those four years (assuming everything else is the same as scenario (1) above)?
