Given : The table shows population data for a community.
To find : percent of change from 2007 to 2013 . predict the population in 2019.
Solution:
Year Population
2007 - 118000
20013 - 138000
Population increased = 138000 - 118000
= 20000
% increase in population = ( 20000/118000) * 100
= 16.95 %
percent of change from 2007 to 2013 is 16.95 %
Population increase in next 6 year = (16.95/100) 138000
= 23391
The predicted population in 2019 is 138000 + 23391
= 161391
The predicted population in 2019 is 161391
