Answer:
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)^ty=a(1+r)
t
y is the population after 3 years i.e. 33278
a is the initial population that is x
r = rate of growth = 0.1
33278=x(1+0.1)^333278=x(1+0.1)
3
x=25000x=25000
Hence the population 3 years ago was 25000
