To determine the population growth rate, we need to follow these steps:
1. Calculate the Birth Rate: This is the number of births per individual in the population over a given period of time. The formula for the birth rate is:
[tex]\[
\text{Birth Rate} = \frac{\text{Number of Births}}{\text{Total Population}}
\][/tex]
- In this case, we have 200 births in a population of 1000 individuals.
- So, the birth rate is:
[tex]\[
\text{Birth Rate} = \frac{200}{1000} = 0.20
\][/tex]
2. Calculate the Death Rate: This is the number of deaths per individual in the population over the same period. The formula for the death rate is:
[tex]\[
\text{Death Rate} = \frac{\text{Number of Deaths}}{\text{Total Population}}
\][/tex]
- Here, we have 100 deaths in a population of 1000 individuals.
- So, the death rate is:
[tex]\[
\text{Death Rate} = \frac{100}{1000} = 0.10
\][/tex]
3. Calculate the Population Growth Rate: The population growth rate is found by subtracting the death rate from the birth rate:
[tex]\[
\text{Population Growth Rate} = \text{Birth Rate} - \text{Death Rate}
\][/tex]
- Using the values calculated above:
[tex]\[
\text{Population Growth Rate} = 0.20 - 0.10 = 0.10
\][/tex]
Therefore, the equation that shows how to calculate the population growth rate for this population is:
[tex]\[
\text{C. } 0.20 - 0.10 = 0.10
\][/tex]
