The population of a town doubles every 12 years. If the population in 1945 was 11,005 people, what was the population in 1981?

Calculate the difference in years:
Difference = 1981 - 1945
Difference = 36

Calculate doubling periods:
Doubling periods = Total years / Doubling time
Doubling periods = 36/12
Doubling periods = 3

Population = Initial Population * 2^doubling periods
Population = 11005 * 2^3
Population = 11005 * 8
Population = 88,040
