Kingfish, Louisiana, had a population of 1,100 individuals. They had a birth rate of 12/100, a death rate of 8/100, and an emigration (individuals leaving the population) rate of 2/100. How many people were added to Kingfish's population in one year?

• A. 2
• B. 6
• C. 20
• D. 1,122
• E. 22

Answer: (E)

Verified step by step guidance

1. Start by identifying the initial population size, which is 1,100 individuals.
2. Calculate the number of births in one year using the birth rate. Multiply the population size by the birth rate: \( \text{Births} = 1100 \times \frac{12}{100} \).
3. Calculate the number of deaths in one year using the death rate. Multiply the population size by the death rate: \( \text{Deaths} = 1100 \times \frac{8}{100} \).
4. Calculate the number of individuals leaving the population due to emigration using the emigration rate. Multiply the population size by the emigration rate: \( \text{Emigration} = 1100 \times \frac{2}{100} \).
5. Determine the net change in population by adding the number of births and subtracting the number of deaths and emigrants: \( \text{Net Change} = \text{Births} - \text{Deaths} - \text{Emigration} \).
