.80X+.30(8-X)=.50*8
\n" ); document.write( ".80X+.24-.30X=4
\n" ); document.write( ".50X=40-.24
\n" ); document.write( ".50X=.16
\n" ); document.write( "X=.16/.5
\n" ); document.write( "X=3.2 LITERS ANS. FOR THE 80% SOLUTION IS USED.
\n" ); document.write( "PROOF:
\n" ); document.write( ".80*3.2+.30(8-3.2)=.50*8
