FV= PV of Annuity Due x (1.09)18; \$100,000 = PV of Annuity Due x (1.09)18; PV of Annuity = 100.000/(1.09)18; PV of Annuity = \$21,199.37 PV of Annuity = Payment x [1.(1.09)-18] /0.09; \$21,199.37 = Payment x 8.7556; Payment = \$21,199.37/8.7556; Payment = \$2,421.24 6. If a widow has \$93,000 investment yielding 9% annually, she can NOT withdraw \$16,000 a year for the next 10 years. PV = Payment x [1-(1.09)-10]/0.09; Pmnt = \$93,000/[1-(1.09)-10]/0.09; Pmnt = \$14,491.26 7. No I will not buy it because the current price is higher than the present value of the investment. PV of Annuity= 10,000 x [1-(1.10)-25]/0.10; PV of Annuity = \$90,770.40 12. FV = PV x (1+r)5; \$100,000 = \$65,000 x (1=r)5; 1.53846 = (1+r)5; (1.53846) 1/5 = 1+r; 1.08998 = 1+r; annual rate = 8.998\$ 13. PV of Annjuity = Payment x [1-(1+r)-5]/r; \$33,520 = \$10,000 x [1-(1+r)-5]/r Period 9nper0 = 5; Payment = \$10,000; Present Value (PV) = \$33,250; Future Value (FV) = \$0; Rate of Return =
