Final answer:
The increase percent is 4%.
Step-by-step explanation:
To find the increase percent, we need to find the difference between the initial population and the final population. The increase is 62500 - 60000 = 2500. To find the increase percent, we divide the increase by the initial population and then multiply by 100. So, the increase percent is (2500 / 60000) * 100 = 4.17%. Rounded to the nearest percent, the increase percent is 4%, option A.
