a. The one-year term rate for ages 21–25

b. The net single premium for a five-year term policy at age 21

c. The net single premium for a five-year endowment at age 21

d. The annual premium for the five-year endowment at age 21 Mortality Table Age Number Alive Number Dying 21 1000 10 22 990 20 23 970 30 24 940 40 25 900 50 Compound Discount Table Present value of $1.00 One year from now = $0.90 Two years from now = $0.80 Three years from now = $0.70 Four years from now = $0.60 Five years from now = $0.50
