Question

The population of one city was about 665,000 in 2010. The population of the city is projected to be about 305,000 in 2020. Find the percent decrease

Answer 1

To find the percent decrease, we need to calculate the difference between the initial population and the projected population, divide that by the initial population, and then multiply by 100.

Difference = 665,000 - 305,000 = 360,000
Percent decrease = (360,000 / 665,000) x 100 = 54.14%

Therefore, the percent decrease in population from 2010 to 2020 is 54.14%.
