一、

discount rate is 10%，present value ：

720*1.1^-1+930*1.1^-2+1190*1.1^-3+1275*1.1^-4

=3188.05

discount rate is 18%，present value ：

720*1.18^-1+930*1.18^-2+1190*1.18^-3+1275*1.18^-4

=2659.98

discount rate is 24%，present value ：

720*1.24^-1+930*1.24^-2+1190*1.24^-3+1275*1.24^-4

=2348.92

二、

discount rate is 8%，future value ：

1375*1.08^3+1495*1.08^2+1580*1.08^1+1630*1.08^0

=6818.27

discount rate is 11%，future value ：

1375*1.11^3+1495*1.11^2+1580*1.11^1+1630*1.11^0

=7106.28

discount rate is 24%，future value ：

1375*1.24^3+1495*1.24^2+1580*1.24^1+1630*1.24^0

=8509.52

三、

a.現在立即存入5000，45年後的價值

=5000*1.11^45=547,651.21

b.10年後存入5000，45年後的價值

=5000*1.11^35=192,874.26
