利用复利公式和复利系数确定下列系数值（F/A,11.5%,10)(A/P,10%.8.6)(P/A,8.8%,7.8)(A/F,9.5%,4.5)

Question

利用复利公式和复利系数确定下列系数值
（F/A,11.5%,10)
(A/P,10%.8.6)
(P/A,8.8%,7.8)
(A/F,9.5%,4.5)

Answer 1

（F/A,11.5%,10)=A*[(1+11.5%)^10]/11.5%=17.13A
(A/P,10%.8.6)=P[10%/[1-(1+10%)^-8.6]=0.179P
(P/A,8.8%,7.8)=A{[1-(1+8.8%)^-7.8]/8.8%}=5.478A
(A/F,9.5%,4.5)=1/[A*[(1+9.5%)^4.5-1/9.5%]=0.188F
