Answer 1

this is the solution of your question

Answer 2

Answer:

25000

Step-by-step explanation:

Let x be the population 3 years ago

The annual rate of growth in population of a town is 10%

So, r = 10%

Formula : $y=a(1+r)^t$

y is the population after 3 years i.e. 33275

a is the initial population that is x

r = rate of growth = 0.1

$33275=x(1+0.1)^3$

$x=25000$

Hence  the population 3 years ago was 25000
