.80x+.30(800-x)=.60*800
\n" ); document.write( ".80x+240-.30x=480
\n" ); document.write( ".50x=480-240
\n" ); document.write( ".50x=240
\n" ); document.write( "x=240/.5
\n" ); document.write( "x=480 ml of 80% solution is used.
\n" ); document.write( "800-480=320 ml of 30% solution is used.
\n" ); document.write( "Proof:
\n" ); document.write( ".80*480+.30*320=.60*800
\n" ); document.write( "384+96=480
\n" ); document.write( "480=480
\n" ); document.write( "
