- How many years will it take for $100,000 to grow to $500,000 if it is invested at an annual interest rate of 9.15%? Round to the nearest 0.01.
- You are told that if you invest $5,000 per year for 35 years you will have accumulated $1,000,000. What is the annual rate of return on the latter investment? Round to the nearest 0.01%.
a.We use the formula:
r=rate of interest
Taking log on both sides;
log 5=n*log (1.0915)
n=log 5/log (1.0915)
b.Putting into financial calculator;
Solving for I/Y;we get;
I/Y=annual rate of return=8.67%(Approx)
