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
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%.
To find the percent decrease in population, you can use the following formula:
Percent decrease = (original population - new population) / original population * 100
Given data:
Original population (2010) = 665,000
New population (2020) = 305,000
Let's substitute these values into the formula:
Percent decrease = (665,000 - 305,000) / 665,000 * 100
Simplifying the equation:
Percent decrease = 360,000 / 665,000 * 100
Calculating the result:
Percent decrease ≈ 54.14%
So, the percent decrease in population is approximately 54.14%.
