<PRE><B>Question 108319</B>
The U.S. population in {{{1990}}} was approximately {{{250}}} {{{million}}}, and the average growth rate for the past {{{30}}} years gives a doubling time of {{{66}}} years. The formula is:

{{{P (in- millions) = 250 * 2(y-1990)/66}}}

What will the population of the United States be in {{{2025}}} if this growth rate continues? 


{{{P=250*2(2025-1990)/66}}}
{{{P=250*2(35/66)}}}….divide {{{2}}} and {{{66}}} by {{{2}}}
{{{P = 250*(35/33)}}}

{{{P=250*1.06}}}
{{{P=265-million}}}
