You can put this solution on YOUR website!
Let n be the amount of 50% solution. Then:
\n" ); document.write( "n(.50)+(8-n)(.20)=8(.3)
\n" ); document.write( ".5n-.2n+1.6=2.4
\n" ); document.write( ".3n=.8
\n" ); document.write( "n=.8/.3=2.67 pints of 50% solution; 5.33 pints of 20% solution!!!!!!!!!!!!!
\n" ); document.write( "
\n" );
