To determine the population of the town after 2 years, given its current population is 4000 and it increases at a rate of 15% per year, we'll follow these steps:
1. Initial Setup:
- Current population: 4000
- Growth rate: 15%, which is equivalent to a multiplier of 1.15 per year.
2. Calculate the population after the first year:
- Population after 1 year = Initial population Growth rate
- Population after 1 year = 4000 1.15
- From this calculation, the population after 1 year is 4600.
3. Calculate the population after the second year:
- Using the population at the end of the first year, we apply the growth rate again.
- Population after 2 years = Population after 1 year Growth rate
- Population after 2 years = 4600 1.15
- From this calculation, the population after 2 years is 5290.
Thus, after 2 years, the population of the town will be 5290.
Correct answer is A. 5290
