$\"+100t%5E2+%2B+300t+%2B+50000+\"$
\n" ); document.write( "= population $\"+t+\"$ yrs after 2000
\n" ); document.write( "------------------------------
\n" ); document.write( "When the year is 2000, $\"+t=0+\"$
\n" ); document.write( " $\"+2000+%2B+t+=+2000+%2B+0+\"$
\n" ); document.write( "Plug $\"+t=0+\"$ into equation
\n" ); document.write( " $\"+100%2A0%5E2+%2B+300%2A0+%2B+50000+=+50000+\"$
\n" ); document.write( "---------------------------------------
