How much would Keith have in his account after three years if he started with $200 and earns 2 percent interest, compounding annually?
Compound interest means earning interest on the interest and principal balance from previous years!
After 1 year, $200 x 1.02 = $204
After 2 years, $204 x 1.02 = $208.08
After 3 years, $208.08 x 1.02 = $212.24
Answer:
The amount after 2 year will be $212.2416
Explanation:
We have given principle amount P = $200
Time period n = 3 years
Rate of interest r = 2 %
We have to find the amount after 2 years if the amount is compounded annually
We know that amount is given by
\(A=P(1+\frac{r}{100})^n\)
\(A=200(1+\frac{2}{100})^3\)
\(A=$212.2416\)
So the amount after 2 year will be $212.2416
