Glenn has made contributions of $250 at the end of every 3 months into an RRSP for 10 years. Interest for the first 10 years was 4% compounded quarterly.

1. What is the amount in the RRSP after the first 10 years?
2. After the first 10 years, Glenn stopped making contributions. The interest rate changed to 5% compounded monthly. How much will Glenn have in his RRSP three years after the last contribution?
3. Suppose Glenn then decides to withdraw the money from his RRSP. How much will he be able to withdraw in monthly amounts over the next 10 years?
