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

The solution for this question will employ the percentage change formula, which is as:Percentage Change[tex] =\frac{New Value - Old Value}{Old Value} \times 100 [/tex]%We know that the population increased from an old value of 25000 to a new value of 30000. Thus, the Old Value is 25000 and the New Value is 30000. Therefore, applying the Percentage Change Formula we get:Percentage Change=[tex] \frac{30000-25000}{25000} \times 100=20% [/tex]Therefore, the percent of increase for a population that changed from 25,000 to 30,000 is 20%.
