Question

the population of the US was 282 million in the year 2000. and 309 million in the year 2010. assuming that the US population follows the model of uninhibited population growth, what will the population be in the year 2050?

Answer 1

417 million

Explanation:

309 minus 282 equals 27. That's how many people moved in 10 years.

Multiply 27 by 4 to get 108. That's how many people will move in 40 years.

Add that to 309 (the amount of people that were living in the U.S. in 2010) to get 417.
