Question 1134185
the united states population increased from 27.3 million people between 2000 and 2010.


that was a 9.7% increase.


let x = the population in 2000.


the increase is therefore .097 * x.


since the increase is 27.3 million people, then .097 * x = 27.3 million.


solve for x to get x = 27.3 / .097 = 281.443299 million.


the population in 2000 was 281.443299 million.


the increase between 2000 and 2010 was 27.3 million.


that means that the population in 2010 was 308.743299 million.


308.743299 / 281.443299 = 1.097.


that's an increase of (1.097 - 1) * 100 = 9.7%.


the solution looks good.


the solution is that there were 281.443299 million people in the united states in the year 2000 and 308.743299 million people in the united states in the year 2010.
