Answer 1

To find the absolute change in population from 2007 to 2009, we can subtract the initial population in 2007 from the final population in 2009:

Absolute change = Final population - Initial population

= 6,200 - 3,900

= 2,300 people

Therefore, the absolute change in population from 2007 to 2009 is 2,300 people.

To find the percent increase (relative change) in population, we can use the formula:

Percent increase = (Absolute change / Initial population) x 100%

Substituting the values given in the problem, we get:

Percent increase = (2,300 / 3,900) x 100%

= 58.97%

Therefore, the population increased by approximately 58.97% from 2007 to 2009. Rounded to the nearest tenth of a percent, the percent increase is 59.0%.
