A chemist has a 30% acid solution and a 50% acid solution. How many liters of each solution does the chemist need to make 100 liters of a 38% acid solution.
\n" ); document.write( "***
\n" ); document.write( "let x=amount of 30% solution needed
\n" ); document.write( "100-x=amount of 50% solution needed
\n" ); document.write( "..
\n" ); document.write( "30%x+50%(100-x)=38%*100
\n" ); document.write( ".30x+50-.50x=38
\n" ); document.write( ".20x=12
\n" ); document.write( "x=60
\n" ); document.write( "100-x=40
\n" ); document.write( "amount of 30% solution needed=60 liters
\n" ); document.write( "amount of 50% solution needed=40 liters
\n" ); document.write( "
\n" );
