\n" );
document.write( "Let x represent the amount of salt added. Note: that is a 100% solution of salt.
\n" );
document.write( ".20*60kg + 1.00x = .40(60kg + x)***
\n" );
document.write( "solve for x
\n" );
document.write( ".6x = .20*60kg
\n" );
document.write( "x = 20 kg of salt needs to be added\r
\n" );
document.write( "\n" );
