peanut pounds=p
\n" ); document.write( "walnut pounds=w
\n" ); document.write( "p+w=100
\n" ); document.write( "2.49p+3.49w=299 (2.99*100)
\n" ); document.write( "but p=(100-w)
\n" ); document.write( "2.49(100-w)+3.49 w=299
\n" ); document.write( "249-2.49w +3.49 w=299
\n" ); document.write( "w=50 lb
\n" ); document.write( "p=50 lb
\n" ); document.write( "Notice that this makes sense, since the price of the combination is exactly between the price of each, so each one constitutes half.
\n" ); document.write( "
\n" );
