A grey squirrel population was introduced in a certain county of Great Britain 35 years ago. Biologists observe that the population doubles every 7 years, and now the population is 80,000.

Estimate the squirrel population 10 years from now.

Let g be the growth rate

x(1+g)^{7 } =2x

or

(1+g)^{7 } =2

g= 2^{1/7}-1= 0.104089514

After 10 years , 80000(1.10409)^{10 } =80000* 2.691800385= 215344
