Question

In 2009, the population of Mexico was about 111.2 million, and the exponential growth rate was 1.13% per year.a) Estimate the population in 2016. b) After how long will the population be 150 million?

Answer 1

ok, so multiply 1.13% by the number of years it takes to get from 2009-2016, then do 111.2 million times the answer you got for that and add that to 111.2 million and you will have the answer for a.

Answer 2

for b:
on a calculator do 111.2 million * 1.13% then do 150 million-111.2 million. after that you want to divide that by the number you got for 111.2 million* 1.13% and you will have your answer.
