Solution:
Original Population of elk= 1537
Population after a year =1537 × 1.076
Let rate at which Population of elk is increasing = R %
Let In the beginning the population of elk= P
t= Time after which population is to be found
E(x)=Population of elk after time t,that is E(0)=P
So, Writing the formula at the rate which population of elk is increasing:
⇒E(x)=
E(1)= 1537
⇒1537=
1537=
E(2)= 1537 × 1.076=1653.812
⇒ 1653.812=
E(9)= 1537
As P is population when t=0, so we have to find population after 9 years , as is population when t=1,so considering
as initial population, so, t=8
E(9)=
= 1537 × 1.796
= 2761.6716
= 2761.68 (Approx)
