\n" ); document.write( "-----
\n" ); document.write( "Equation::
\n" ); document.write( "salt + salt = salt
\n" ); document.write( "1*x + 0.05*9 = 0.15(x+9)
\n" ); document.write( "100x + 5*9 = 15x + 15*9
\n" ); document.write( "85x = 10*9
\n" ); document.write( "x = 1.06 ounces (amt. of pure salt to add)
