.36x+.03(33-x)=.18*33
\n" ); document.write( ".36x+.99-.03x=5.94
\n" ); document.write( ".33x=5.94-.99
\n" ); document.write( ".33x=4.95
\n" ); document.write( "x=4.95/.33
\n" ); document.write( "x=15 L 0f 36% butterfat is used.
\n" ); document.write( "33-15=18 L of 3% butterfat is used.
\n" ); document.write( "Proof:
\n" ); document.write( ".36*15+.03*18=.18*33
\n" ); document.write( "5.4+.54=5.94
\n" ); document.write( "5.94=5.94
