a+b=50.6,
\n" ); document.write( "0.045*a+0.023*b=0.035*50.6
\n" ); document.write( "a=50.6-b
\n" ); document.write( "0.045*(50.6-b)+0.023*b=1.771
\n" ); document.write( "2.277-0.045b+0.023*b=1.771
\n" ); document.write( "-0.022*b=-0.506
\n" ); document.write( "b=23.0
\n" ); document.write( "a=50.6-b
\n" ); document.write( "a=27.6 lb at $4.50 b=23.0 lb at $2.30
\n" ); document.write( "check
\n" ); document.write( "0.045*27.6+0.023*23.0=0.035*50.6
