A scientist needs 60 liters of a 60% acid solution. He currently has a 40% solution and a 70% solution. How many liters of each does he need to make the needed 60 liters of 60% acid solution?
\n" ); document.write( "----------------
\n" ); document.write( "Equation:
\n" ); document.write( "acid + acid = acid
\n" ); document.write( "----------------------
\n" ); document.write( "0.40x + 0.70(60-x) = 0.60*60
\n" ); document.write( "-----
\n" ); document.write( "40x + 70*60 - 70x = 60*60
\n" ); document.write( "-----
\n" ); document.write( "-30x = -10*60
\n" ); document.write( "x = 20 liters
\n" ); document.write( "----
\n" ); document.write( "Gabe needs 20 liters of the 40% solution.
\n" ); document.write( "He also needs 40 liters of the 70% solution.
