Explanation

Increase from 2000 to 2010 = 50,000. Projected increase from 2010 to 2020 = 50,000. Percent increase = (Increase / Population in 2010) * 100 = (50,000 / 700,000) * 100 = 5/70 * 100 = 1/14 * 100 = 7.14%.

AI explanation

The absolute increase in population from 2000 to 2010 is calculated as 700,000 minus 650,000, which equals 50,000. The projected percent increase from 2010 to 2020 is this same absolute increase of 50,000 divided by the 2010 population of 700,000. Performing the division 50,000 / 700,000 yields approximately 0.0714. Multiplying by 100 gives an approximate percent increase of 7.1%. The result is 7.1%.
