Question:

Reconsider Table 21-1, and assume that as in Problem 21-23, you wish to save enough this year to have $50,000 available for your planned retirement 30 years into the future. How many dollars would you have to save this year to ensure that a total amount of $50,000 would be accumulated 30 years into the future if the interest rate appropriate for discounting decreases to 3 percent?
