To find the population after n years,
Multiply the initial population by (1 + annual growth rate)n.
Solution:
After the first year: 2000 × (1 + 0.002) = 2004.
After the second year: 2004 × (1 + 0.004) = 2012.02.
After the third year: 2012.02 × (1 - 0.004) = 2003.97.
Therefore, the population of the village after 3 years will be approximately 2003.97.
