# Increase in population of United States

129. Population of the United States. In 2006 the population

of the United States was 300.2 million (U.S. Census

Bureau, www.census.gov). If the population continues to

grow at an annual rate of 1.05%, then the population in

the year 2020 will be 300.2(1.0105)14 million.

a) Evaluate the expression to find the predicted population

in 2020 to the nearest tenth of a million people.

b) Use the accompanying graph to estimate the year in

which the population will reach 400 million people.

130. Population of Mexico. In 2006 the population of

Mexico was 107.4 million. If Mexico's population continues

to grow at an annual rate of 1.43%, then the population

in 2028 will be 107.4(1.0143)14 million.

a) Find the predicted population in 2020 to the nearest

tenth of a million people.

b) Use the result of Exercise 129 to determine whether

the United States or Mexico will have the greater

increase in population between 2006 and 2020.
