How many liters of a 25% salt solution must be added to 20 liters of a 12% solution to get a solution that is 20% salt?
\n" ); document.write( "-------
\n" ); document.write( "Equation:
\n" ); document.write( "salt + salt = salt
\n" ); document.write( "0.25x + + 0.12*20 = 0.20(x+20)
\n" ); document.write( "-----
\n" ); document.write( "25x + 12*20 = 20x + 20*20
\n" ); document.write( "-----
\n" ); document.write( "5x = 8*20
\n" ); document.write( "x = 8*4 = 32 liters (amt of 25% solution to add)
\n" ); document.write( "---------
