\n" ); document.write( "***
\n" ); document.write( "let x=amt of 20% solution to mix
\n" ); document.write( "20%x+80%*40=40%(x+40)
\n" ); document.write( ".20x+32=.40x+16
\n" ); document.write( ".20x=16
\n" ); document.write( "x=80
\n" ); document.write( "amt of 20% solution to mix=80 liters
\n" ); document.write( "
\n" );
