If 10 human couples move into a new unpopulated area, how many people will live in the area after 200 years? The couples are 20 years old when they move. The people's life expectancy is 60 yeras, the average family has 4 children, and the average couple begins having children at age 20 and ends at 30.

Are you assuming that no one moves away and no one moves in?

If so -- then the population doubles every 25 years.



Thanks!! i guess it's assuming no one moves away and no one moves in, because that's all it said in the problem. but how did you figure out that it doubles every 25 years??

and so is the answer 5120 people??
