Final answer:
To calculate the population in 4 years, use the formula: New Population = Current Population + (Current Population * Growth Rate). Given the current population is 15,200 and the growth rate is 9%, the population will be approximately 16,568 in 4 years.
Step-by-step explanation:
To calculate the population in 4 years, we can use the formula:
New Population = Current Population + (Current Population * Growth Rate)
Given that the current population is 15,200 and the growth rate is 9%, we can plug in these values into the formula:
New Population = 15,200 + (15,200 * 0.09)
Simplifying the equation:
New Population = 15,200 + 1,368
New Population = 16,568
Rounding to the nearest whole number, the population will be approximately 16,568 in 4 years.
