The population decline 21 %down to 15,049 what is the population

Hello! To follow up on Spencer9661's answer, I will explain how we got to the correct answer of about 19,049 people. First, take 100% - 21% to equal 79%. (15,049 is 79% of the total population) then, set up a proportion and find x. What I did was 79/100=15,049/x. Cross multiply, and you get 79x=1,504,900. Divide 1,504,900 by 79 to get x=19,049.367

The answer is about 19049
