Explanation:
The first is asking for today's worth of the investment,which is the amount to be invested,this can be computed using the present value as shown below:
PV=FV*(1+r)^-n
PV is the present value
FV is the worth of the investment in 4 years from now which is $80,000
r is the rate of return of 8%
n is the number of years of investment which is 4 years
PV=$80,000*(1+8%)^-4
PV=$80,0008(1+0.08)^-4
PV=$80,000*(1.08)^-4
PV =$ 58,802.39
interest for four years=FV-PV
interest for four years=$80,000-$ 58,802.39
=$21,197.61
