4) A)Compute the present value of an annuity stream in which the first payment is due in 10 years, and annual payments occur forever. The first payment is $445. Subsequent payments shrink at an annual rate of -4.0% per year. Use an effective annual rate (EAR) of 7.50%.

B) Compute the future value (that coincides with the last payment of a finite annuity stream). The first payment is in one year, and the subsequent 20 payments are all $500 per year (g = 0). Use an effective annual rate (EAR) of 12.3%.

Enter your answer as a positive value.

C) Compute the present value of a finite annuity stream. The first payment occurs in one year, and the last payment occurs 12 years from today. The first payment will be $300. Subsequent payments will grow at an annual rate of 5.0%. Use an effective annual rate (EAR) of 9.25%.

D)Compute the present value of a finite annuity stream. The first payment occurs in 5 years, and the last payment occurs 20 years from today. The first payment will be $200. Subsequent payments will grow at an annual rate of 10%. Use an effective annual rate (EAR) of 12.5%.
