Answer:
c. $8,062.31 in nominal terms.
Step-by-step explanation:
The portfolio value required which is at the end of 20 years is the future value of the amount invested initially($1000) , compounded at the nominal rate of return 11% per year as shown below:
FV=PV*(1+nominal interest rate)^n
PV=present value=initial invested=$1000
nominal interest rate=11%
n=time horizon of the investment=20 years
FV=$1000*(1+11%)^20= 8,062.31
