What is the percent of increase for a population that changed from 438,000 to 561,000?

Sagot :

To get the answer we can use proportion. We know that 438000 its 100% and we want to know how much its 561000.
438000 ------------ 100%
561000 ------------ x
Crossmultiply now
438000*x=561000*100%
438000x=56100000     /:438000 (divide both sides by 438000)
x=128%
Finally we have to subtract 128%-100%=28% to get percent of increase.
The answer is 28%.

find out how much 561000 goes over 438000, which would be 123000. then you divide to find out the ratio or percentage of the increase from 438000 would be. 123000/438000=.2808219178 so .28 so 28%.
