You can put this solution on YOUR website!
Let $\"+s+\"$ = Staceyville's original population
\n" ); document.write( "Let $\"+n+\"$ = number of years passed
\n" ); document.write( "after 1 yr - 2s
\n" ); document.write( "after 2 yrs - 4s
\n" ); document.write( "after 3 yrs - 8s
\n" ); document.write( " $\"+s%2A2%5En+\"$ is population after $\"n\"$ years
\n" ); document.write( "---------------
\n" ); document.write( "Mc Peakland's population after $\"n\"$ yrs is
\n" ); document.write( " $\"+145000%2A3%5En+\"$
\n" ); document.write( "---------------
\n" ); document.write( "given:
\n" ); document.write( " $\"+s%2A2%5E24+=+145000%2A3%5E24+\"$
\n" ); document.write( " $\"+s+=+145000%2A%283%5E24%2F2%5E24%29+\"$
\n" ); document.write( " $\"+s+=+145000%2A%283%2F2%29%5E24+\"$
\n" ); document.write( "You can solve this with logs
\n" ); document.write( " $\"+log%28s%29+=+log%28145000%29+%2B+24%2Alog%28+1.5+%29+\"$
\n" ); document.write( " $\"+log%28s%29+=+log%281.45%29+%2B+log%28+10%5E5%29+%2B+24%2Alog%28+1.5+%29+\"$
