George, age 50, is considering purchasing two annuities: a 20-year annuity certain with an annual benefit of $10,000 payable continuously, or a 20-year temporary life annuity with an annual benefit of $10,000 payable continuously. The cost for either annuity is its net single premium. George opts for the temporary life annuity, and he invests the savings (the difference in net single premiums) immediately. George survives 20 years. You are given that =0.04 and =0.06. Determine the value of the invested savings after 20 years.
