In 2012 the population of a city was 5.44 million. The exponential growth rate was 1.86% per year. At what year would the population double?

Answer 1

2 = e^.0186t take natural logs of both sdies

ln2 = 0.0186t divide by the growth rate, 0.0186

t = ln2/0.0186 = about 37.3 years, the year 2049 or 2050 the city will reach 10.88 million

2012+37.3 = 2049.3 maybe 3 months into 2050
