I tried to answer this problem.
Jane was studying a penguin colony which had approximately 1000 penguins. Each year 20% die from natural causes. There are an equal number of males and females. One male and one female are a couple and each couple has one chick. How many penguins will be in the colony after 7 years? What formula would you use to determine the number of penguins?
I got around 210. I just used the usual decay formula but I am not sure if this is correct the part ""There are an equal number of males and females. One male and one female are a couple and each couple has one chick." makes me confused. Is that part an unnecessary information? Or it's needed to solve the problem?
