Let $\"x\"$ = pounds of other ingredients to add
\n" ); document.write( "Oats in 1000 pounds = $\".9%2A1000+=+900\"$
\n" ); document.write( " $\"900%2F%281000+%2B+x%29+=+.8\"$
\n" ); document.write( " $\"900+=+.8%2A%281000+%2B+x%29\"$
\n" ); document.write( " $\"900+=+800+%2B+.8x\"$
\n" ); document.write( " $\".8x+=+100\"$
\n" ); document.write( " $\"x+=+125\"$
\n" ); document.write( "125 pounds of other ingredients must be added
