a+b=170,
\n" ); document.write( "0.4*a+0.65*b=0.55*170
\n" ); document.write( "a=170-b
\n" ); document.write( "0.4*(170-b)+0.65*b=93.5
\n" ); document.write( "68-0.4b+0.65*b=93.5
\n" ); document.write( "0.25*b=25.5
\n" ); document.write( "b=102
\n" ); document.write( "a=170-b
\n" ); document.write( "a=68 oz. at 40%
\n" ); document.write( "b=102 oz. at 65%
\n" ); document.write( "check
\n" ); document.write( "0.4*68+0.65*102=0.55*170
\n" ); document.write( "27.2+66.3=93.5
\n" ); document.write( "93.5=93.5
