ok, i'm doing this research project on libya. its population in 2004 was 5.5 million. the growth rate is 3.59%. i need to find out the population of this country in the year 2025. what is the answer? and please tell me the equation you used so i know for next time.

This is an exponential growth equation.
P = 5.5million(1.0359)^21
1.0359 = 103.59% .....100% of the current population remains and an additional 3.59% is added to the current population each year.
The population will be 11,535,520
Of course, this is a high estimate. Most populations do not follow a strictly exponential growth pattern.

I'll give you the equation and you can solve it.
P= 5.5 x (1.0359)^21 , where P is the 2025 population in millions. This is similar to a compound interest equation, where you deposit 55 dollars in 2004 at 3.59% yearly interest and want to know its worth in 2025. Roughly, the population will double in 2025.

5.5 * (1.0359)^n, where n=2025-2004=21 years.

y= Ce^(kt)
where y=final population
C=initial population
k= growth rate
t= time

I found it by using the compound interest equation. Works just as good for people as it does for money and they're web references galore.

5.5(1.039)^21 = 11.5355
