Using your present and future value tables, calculate the following:

a. Compute the amount that a $50,000 investment today would accumulate to at 10% interest, compounded semiannually, by the end of 6 years.

b. Joe wants to retire at the end of this year (2021). His life expectancy is 20 years from his retirement. Joe has come to you to learn how much he should deposit on December 31, 2021 to be able to withdraw $60,000 at the end of each year for the next 20 years, assuming the amount on deposit will earn 7% interest compounded annually.
