Answer 1

21,525,244

Explanation:

In 2000 the population of a country was 25,300,987.

The population decreased at rate of 2% each year.

Let t=0 since year 2000.

For 2008, t=8

Initial Population, P₀ = 25,300,987

Rate of decrease, r = 0.02

Time in year, t = 8

Formula:

`P=P_0(1-r)^t`

`P=25300987(1-0.02)^8`

`P=25300987(0.98)^8`

`P\approx21525244`

Hence, The population was 21,525,244 in 2008
