You can put this solution on YOUR website!
Call the amount of 40% solution, x.
\n" ); document.write( "Then the amount of 25% used is 128 - x.
\n" ); document.write( "The set up looks like this:
\n" ); document.write( "x(.40) + (128-x)(.25) = 128(.34)
\n" ); document.write( ".4x + 32 - .25x = 43.52
\n" ); document.write( ".15x = 11.52
\n" ); document.write( "x = 11.52/.15 = 76.8 liters of 40% solution
\n" ); document.write( "128-x = 51.2 L of 25% solution
\n" ); document.write( "
\n" );
