10. Annuities (APPS) N Number of payments made –years I% Annual interest rate –%, not a decimal PV 0 PMT Your periodic payment – as a negative (-) FV Value of the account after N payments P/Y Number of payments per year C/Y Number of compoundings per year 10 5.4 Retirement Funds

11. 13 of 30 Using APPS verify that Alaysia will have \$442,493 ? + + = \$0 10% \$1,000 Age 65 N = I% = PV = PMT = FV = P/Y = C/Y = 5.4 Retirement Funds
