Expert Solution
Step 1
Given,
Initial population of a town is 5000 persons.
It is given that it increases at a rate of 2% every year.
Here we shall use the exponential growth formula.
Here P is the final population, is initial population, r is the rate of growth and t is time in years.
Step 2
Now we shall plug the values in formula we get,
Hence after 7 years population shall be 5743.
