\n" ); document.write( "-----
\n" ); document.write( "fat + fat = fat
\n" ); document.write( "0.40x + 0.20*1000 = 0.36(x+1000)
\n" ); document.write( "Multiply thru by 100 to get:
\n" ); document.write( "40x + 200 = 36x + 36000
\n" ); document.write( "4x = 35800
\n" ); document.write( "x = 8950 ml (amt. of 40% butterfat needed for the mixture)
