\n" ); document.write( "\n" ); document.write( "Denote the 50% solution as x and the 70% solution as y.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Then 70-50=20 and 80-70=10\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x/y=1/2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Then x=(1/3)(20)=6.67 L (Answer) and y=20-6.67=13.33 L (Answer)
\n" ); document.write( "
