Answer:
Step-by-step explanation:
Given that initial population is 3100
The population is decreasing continuously which means the population at any time t can be represented by the funciton
![P = P_0 e^{-rt}](https://tex.z-dn.net/?f=P%20%3D%20P_0%20e%5E%7B-rt%7D)
where t = time and r = rate
The population is continuously decreasing at the rate of r% per unit of time.
When t becomes very large,
we get limit would be P0 (0) =0
The population will decrease and almost tend to 0 as time advances.
There is no chance for further decrease as population cannot be negative
So limiting population is 0.
