It is very simple. You have the formula, just plug in the values.Originally Posted by santos
This is reaally important.
The formula P=Po(1+r)^n gives the population P at the end of an n-year time period, where Po is the initial population and r is the average anual growth rate. The U.S. Population grew from 248.7 million in 1990 to 294.4 million in 2004 (US Census Bureau). Find the average anual rate of growth for the US population for that period.
I have tried the numbers in the formula, but i don't know how to solve it. Quick Responses with the answer is greatly appreciated. Thank You.
Read the problem again . . . and ignore any extraneous information.
The population grew from 248.7 million to 294.4 million from 1990 to 2004.The U.S. Population grew from 248.7 million in 1990 to 294.4 million in 2004.
Find the average annual rate of growth for the US population for that period.
That's an increase of million in years.
Therefore, the average growth is: . million per year.
