A Correct answer
Explanation

Population = P * (1 + 5/100)^2 = 44100. P * (1.05)^2 = 44100. P * 1.1025 = 44100. P = 44100 / 1.1025 = 40000.

AI explanation

To find the past population from a present population with annual growth, use the formula Past = Present / (1 + r/100)^n. Substituting the values gives 44100 / (1.05)^2 = 44100 / 1.1025. This calculation results in a 2010 population of 40,000.
