5. How long will it take $5,000 to become $8,000 when the $5,000 grows at 9.5 percent per year?
Group of answer choices
A. 6.26 years
B. 6.11 years
C. 5.18 years
D. 5.79 years
E. 5.35 years
We use the formula:
A=P(1+r/100)^n
where
A=future value
P=present value
r=rate of interest
n=time period.
8000=5000*(1.095)^n
(8000/5000)=(1.095)^n
Taking log on both sides;
log (8000/5000)=n*log 1.095
n=log (8000/5000)/log 1.095
=5.18 years(Approx)
