You need to have $1000 in two years. You want to save an equal amount next year and the following year (at years one and two) to have this
$1000. The interest rate for the first year is 4% and the rate for the second year is 6.5%. What is the amount you need to save?
Assume you have $10000 in the bank now and you will deposit and additional $5000 a year for the next 20 years (as a regular annuity).
You will then withdraw the money as a regular annuity over the next ten years. If the interest rate is 10% for the
entire period what are the amounts of the annuity withdrawals?
