Question

An invasive species of rodent is spreading across the south. The initial population was estimated at 400 individuals in 2010, but the population has been growing by 58% every year. How many of these rodents can we expect by the year 2025 if the rate they are spreading remains the same?

Answer 1

Population = 400*(1.58)^y in 2010
Where y is the number of years
So we could expect 632 by 2011
and after 15 years (the year 2025) the population will be
400*(1.58)^15
= 381,871
