\n" ); document.write( "The amt of salt remains the same
\n" ); document.write( "let x = amt of water added
\n" ); document.write( "1.6 = .05(x+20)
\n" ); document.write( "1.6 = .05x + 1
\n" ); document.write( "1.6 - 1 = .05x
\n" ); document.write( "x = .6/.05
\n" ); document.write( "x = 12 lb of water added \n" ); document.write( "
