Question

In 2011 Chicago's population was 2,707,000, an increase of 0.4% compared to the previous year what would the equation look like

Answer 1

Population = 2,707,000 * 1.004^n where 'n' = the present year minus 2011

So the population would be
2010 2,707,000 * 0.9960159363 2,696,215
2011 2,707,000 * 1 2,707,000
2012 2,707,000 * 1.004 2,717,828
2013 2,707,000 * 1.008016 2,728,699
2014 2,707,000 * 1.012048064 2,739,614
2015 2,707,000 * 1.0160962563 2,750,573
2016 2,707,000 * 1.0201606413 2,761,575
