.50x+.10(1300-x)=.40*1300
\n" ); document.write( ".50x+130-.10x=520
\n" ); document.write( ".40x=520-130
\n" ); document.write( ".40x=390
\n" ); document.write( "x=390/.40
\n" ); document.write( "x=975 gal. of 50% juice is used.
\n" ); document.write( "1300-975=325 gal of 10% juice is used.
\n" ); document.write( "Proof:
\n" ); document.write( ".50*975+.10*325=.40*1300
\n" ); document.write( "487.5+32.5=520
\n" ); document.write( "520=520
