Problem

In 1990 the Department of Natural Resources released 1000 splake (a crossbreed of fish) into a lake. In 1997 the population of splake in the lake was estimated to be 3000. Using the Malthusian law for population growth, estimate the population of splake in the lake in the year 2020.

Step 1</p>

In this problem, we have to calculate the population of splake in the lake in year 2020.

Step 2</p>

Here, we use the concept of population Growth decay

General equation of population Growth decay will be

Where p(t) be the number of population at time t ,be the initial population at t = 0 and k be a constant.
