In 2004, the population of Mexico was 106.5 million. If Mexico's population continues to grow at an annual rate of 1.43%, then the population in 2015 will be 106.5 (1.0143)^11 million.
a. find the predicted population in 2015 to the nearest tenth of a million people.
b. With these US results,
1. 330.2 million  predicted US population in 2015 to the nearesth tenth of a million people.
b. 2022  the estimated year in which the population will reach 350 million people,determine whether US or Mexico will have the greater increase in population between 2004 and 2015.
1a. 106.5*1.0143)^11 = 124.5 million
(for Mexico in 2015)
If the US has 330.2 million in 2015 and 350 million ion 2022, its annual growth rate x for 20152022 is given by
(1+ x)^7 = 350/330.2
x = 0.00835 (0.835% growth per year).
The growth rate in the US for 20152022, is less than that of Mexico for 20042015. You have not provided any data for the US for 20042015.
