Directions: The population
of the United States was 76
million in the year 1900.
During the 20th century the
population increased by
270%. Use variables and an
equation to show how you
would find the population in
the year 2000. Next use the
equation to find the actual
value.
If the U.S. population increased another 270% during the 21st century, what will be the
population in the year 2100? Use variables and an equation to show how you would find
the population in the year 2100. Next use the equation to find the actual value.
Do you think the population could get over 1 billion by 2100? Why or why not?
