Future value (FV) = Present Value(PV)*(1+r)n
a) PV =$1, r = 13.7%
n= 1 FV = 1*(1+0.137)1 = 1.137
n= 5 FV = 1*(1+0.137)5 = 1.9002
n= 20 FV = 1*(1+0.137)20 = 13.0379
b) PV =$1, i = 13.5%, r = 0.135/2 = 0.0675
n= 1*2=2 FV = 1*(1+0.0675)2 = 1.1396
n= 5*2=10 FV = 1*(1+0.0675)10 = 1.9217
n= 20*2=40 FV = 1*(1+0.0675)40 = 13.6369
c) compounded continuously P(t) =P0ert
P0= 1, r = 13.3% (0.133), e = 2.7183
t=1 FV = 1*e(0.133*1) = 1*2.7183(0.133*1) = 1.1423
t=5 FV = 1*e(0.133*5) = 1*2.7183(0.133*5) =1.9445
t=20 FV = 1*e(0.133*20) = 1*2.7183(0.133*20) =14.2965
d) c Investment I prefer (compounded continuously)
even the rate of interest is low compared to a&b the FV is high among a&b because of compounded continuously. so i prefer Investment in (c)
