document.write( "With amount of pure salt being S, equation is: .12(25) + S = .2(25 + S)\r\n" );
document.write( "Solving for S, amount of pure salt to be added = \"2%261%2F2\", or 2.5 grams.\r\n" );
document.write( "\r\n" );
document.write( "FYI: The answer is NOT 10 grams, as the other person who responded, states!
