Final answer:
The population is increasing by 2.5% per year. The current population is 66625. In 10 years, the population is predicted to be approximately 83005.
Step-by-step explanation:
Part A: To find the annual increase or decrease in population, we need to determine the change in population from year to year. In this case, the population is increasing every year. The formula given is P = 65000(1 + 0.025), where P represents the population. So, the population is increasing by 2.5% every year.
Part B: To find the current population, we can substitute the given formula into the equation. P = 65000(1 + 0.025) = 65000(1.025) = 66625. Therefore, the current population is 66625.
Part C: To predict the population in 10 years, we can use the given formula and substitute the value for t (which represents the number of years) as 10. P = 65000(1 + 0.025)^10 = 65000(1.025)^10 ≈ 65000(1.277) = 83005. So, we can predict that the population in 10 years will be approximately 83005.
