Note that they gave the starting population to be 10,000 with equal number of males and females.
Question 3: PENGUINS
Jean assumes the colony will continue to grow in the following manner:
At the beginning of each year, the colony consists of equal numbers of male and female penguins who form couples.
Each penguin couple raises one chick in the spring of each year.
By the end of each year 20% of all the penguins (adults and chicks) will die.
One year old penguins will also raise chicks.
Based on the above assumptions, which of the following formulae describes the total number of penguins, P, after 7 years?
A. P= 10 000 x (1.5 x 0.2)7
B. P= 10 000 x (1.5 x 0.8)7
C. P= 10 000 x (1.2 x 0.2)7
D. P= 10 000 x (1.2 x 0.8)7
