Answer 2

The answer is this problem is as follows:

Step-by-step explanation:

present population: 10,000

Increase in year 1= 20%

hence,

20% of 10,000= 20/100 × 10,000

= 2000

Population in year 2 = 12,000

Increase in year 2 = 20%

∴ 20/100 × 12,000

= 2400

Population in year 3 = 14,400

Increase in year 3 =20%

∴ 20/100 × 14,400

= 2880

Therefore,

Population after 3 years is:

=17,280
