1L of a 36% saline solution was mixed with 3L of a 20% saline solution.
\n" ); document.write( " What is the concentration of the mixture.
\n" ); document.write( ":
\n" ); document.write( "let x = the decimal equiv of the per cent salt in the final mixture (4 liters)
\n" ); document.write( ".36(1) + .20(3) = 4x
\n" ); document.write( ".36 + .60 = 4x
\n" ); document.write( ".96 = 4x
\n" ); document.write( "x = .96/4
\n" ); document.write( "x = .24 which is a 24% concentration in the final mixture \n" ); document.write( "

\n" );
