e.
Using the answers from above parts we have to estimate doubling time for the investment.
e.
Answer to Problem 2P
Doubling time is 10 years on a rate of 7.2% compounded annually.
Explanation of Solution
Doubling rate is given by formula,
Where
We have to solve for
Now we put
Hence we get,
Sometimes this is directly used to calculate the doubling time when the interest is compounded annually. (Called rule of 72)
Hence doubling time is
