.01X+.50(8-X)=.20*8
\n" ); document.write( ".01X+4-.50X=1.6
\n" ); document.write( "-.49X=1.6-4
\n" ); document.write( "-.49X=-2.4
\n" ); document.write( "X=-2.4/-.49
\n" ); document.write( "X=4.9 OZ. OF 1% ALCOHOL IS USED.
\n" ); document.write( "8-4.9=3.1 OZ. OF 50% ALCOHOL IS USED.
\n" ); document.write( "PROOF:
\n" ); document.write( ".01*4.9+.50*3.1=.20*8
\n" ); document.write( ".049+1.1.55=1.6
\n" ); document.write( "1.6=1.6\r
