\n" ); document.write( "Let x = amount (grams) of 30% granola
\n" ); document.write( "then
\n" ); document.write( "600-x = amount (grams) of 15% granola
\n" ); document.write( ".
\n" ); document.write( ".30x + .15(600-x) = .21(600)
\n" ); document.write( ".30x + 90-.15x = 126
\n" ); document.write( ".15x + 90 = 126
\n" ); document.write( ".15x = 36
\n" ); document.write( "x = 240 grams (30% granola)
\n" ); document.write( ".
\n" ); document.write( "15% granola:
