4% butterfat = x quarts
\n" ); document.write( "1%butterfat = 6-x quarts
\n" ); document.write( "2% mixture= 6 quarts
\n" ); document.write( "..
\n" ); document.write( "the concentration of individual fats make the final mix.\r
\n" ); document.write( "\n" ); document.write( "0.04x+0.01(6-x)=0.02*6
\n" ); document.write( "0.04x+0.06-0.01x=0.12
\n" ); document.write( "0.03x=0.12-0.06
\n" ); document.write( "multiply the equation by 100
\n" ); document.write( "3x=12-6
\n" ); document.write( "3x=6
\n" ); document.write( "x=2
\n" ); document.write( "
