Answer:

A total of 8926 people will be the population in 20 years

Explanation:

Every year the population decreases by 3.2%.

This means this year, (24806 × 3.2%) will decrease the population.

24806 × 3.2% = 793.792 = 794 rounded up.

So it will decrease by 794 people each year for 20 years.

Therefore 794 × 20 = 15880

So the population in 20 years will be 24806 - 15880 = 8926

So 8926 people will be available in 20 years to come. That's the population in 20 years.
