1.The population of a certain town is increase at rate of 2.5% per year. If the population is 100,000. What is the population be 10 years from now?
To find the population 10 years from now, we need to calculate the annual growth rate and then multiply it by the initial population.
The annual growth rate can be calculated using the formula:
Growth rate = Initial population * (annual rate of increase / 100)
In this case, the initial population is 100,000 and the annual rate of increase is 2.5%. Plugging these values into the formula:
Growth rate = 100,000 * (2.5 / 100) = 2,500
So, the annual growth rate is 2,500.
To find the population 10 years from now, we simply multiply the growth rate by the number of years:
Population after 10 years = Initial population + (Growth rate * Number of years)
Population after 10 years = 100,000 + (2,500 * 10) = 100,000 + 25,000 = 125,000
Therefore, the population of the town will be 125,000 in 10 years.
