Researchers find that there are 60 Raccoons on an island. When they return a year later, they find that there are 84. What is the annual population growth rate for the raccoons?
To calculate the annual population growth rate, you need to find the percentage increase in the population over the year.
First, determine the increase in the population:
Population increase = Final population - Initial population
Population increase = 84 - 60
Population increase = 24
Next, calculate the percentage increase:
Percentage increase = (Population increase / Initial population) * 100
Percentage increase = (24 / 60) * 100
Percentage increase = 40%
Therefore, the annual population growth rate for the raccoons is 40%.
To find the annual population growth rate for the raccoons, you need to calculate the percentage increase in population over the year. Here's how you can do it step by step:
Step 1: Calculate the difference in population.
The initial population is 60 raccoons, and the population a year later is 84 raccoons.
Population difference = final population - initial population = 84 - 60 = 24 raccoons.
Step 2: Calculate the percentage increase.
Percentage increase = (population difference / initial population) * 100
Percentage increase = (24 / 60) * 100 ≈ 40%.
Therefore, the annual population growth rate for the raccoons on the island is approximately 40%.
