Answer 1

2000: 281.4 mill

2010: 308.7 mill

Answer 2

Answer: Population in 200 = 281 million.

Population in 2010 = 308 million

Explanation:

Let x denotes the population in 2000 ( in millions).

Given : According to the report “Population Distribution and Change: 2000 to 2010” from the U.S. Census Bureau, the U.S. population increased by 27.3 million people from 2000 to 2010.

This was a 9.7% increase.

∵ 9.7%=0.097

then, we have
`0.097x=27.3`

Divide both sides , by 0.097, we get

`x=281.443298969\approx281` [Rounded to nearest million]

Hence, the population in 200 = 281 million.

Then, the population in 2010=
`281+27.3=308.3\approx308` million [Rounded to nearest million]
