Calculus/doubling money

Expert: Alon Mandes - 8/7/2008


Question
Doubling ur money: determine how much time is required for an investment to double in value if interest is earned at the rate of 6.25% compounded annually.

Answer
The formula for such future value is : Fv=P(1+r)^n where, Fv
is the future value of the investment,r is the annual interest
& n is the amount of years. Now, we want to double our money, so
2p=p(1+6.25%)^n --> 2=1.0625^n. Let's perform Ln to both sides :
Ln(2)=nLn(1.0625) --> n=11.433 years.
