4) Determine the value at the end of four years of
a $5,000 investment today that pays a nominal annual interest rate of 15%, compounded:
a)
Annually
b)
Semiannually
c)
Quarterly
d)
Monthly
5. You are considering buying a painting by a
local
artist for $1,200. You believe that this artist is just
about to be discovered, and think that five years from now the
painting will be worth $5,000. If you are
correct, what average annual return would you earn on this
investment over this period?
Problem 4
a)
Present value of deposit=PV=$4000
Nominal Rate of interest=r=15%
Number of compounding periods in a year=c=1 (annual compounding)
Nominal interest rate per compounding period=i=r/c=15%/1=15%
Total number of compounding periods=n=number of years*c=4*1=4
FV=PV*(1+i)n=4000*(1+15%)4=$6996.03
b)
Present value of deposit=PV=$4000
Nominal Rate of interest=r=15%
Number of compounding periods in a year=c=2 (semi annual compounding)
Nominal interest rate per compounding period=i=r/c=15%/2=7.5%
Total number of compounding periods=n=number of years*c=4*2=8
FV=PV*(1+i)n=4000*(1+7.5%)8=$7133.91
c)
Present value of deposit=PV=$4000
Nominal Rate of interest=r=15%
Number of compounding periods in a year=c=4 (quarterly compounding)
Nominal interest rate per compounding period=i=r/c=15%/4=3.75%
Total number of compounding periods=n=number of years*c=4*4=16
FV=PV*(1+i)n=4000*(1+3.75%)16=$7208.91
d)
Present value of deposit=PV=$4000
Nominal Rate of interest=r=15%
Number of compounding periods in a year=c=12 (monthly compounding)
Nominal interest rate per compounding period=i=r/c=15%/12=1.25%
Total number of compounding periods=n=number of years*c=4*12=48
FV=PV*(1+i)n=4000*(1+1.25%)48=$7261.42
Problem 5
Purchase value of painting=PV=$1200
Expected future value=FV=$5000
Number of periods=n=5 years
Let the annual return be i. So.
FV=PV*(1+i)n
5000=1200*(1+i)5
4.166667=(1+i)5
(1+i)=(4.166667)1/5
(1+i)=1.330325
i=0.330325 or say 33.03%
