What percent of increase for a population that changed from 25,000 to 30,000
tiny-mole [99]

percent of increase for a population that changed from 25,000 to 30,000

Increase in population = 30,000 - 25,000 = 5000

So, the increase in population is 5000

To find percent of increase , we divide the increase in population by initial population.

So percent of increase = \frac{5000}{25000} * 100

= 0.2 * 100

= 20 %

20% of increase for a population that changed from 25,000 to 30,000.
