\n" ); document.write( "\n" ); document.write( "Let amount of 4% butterfat milk to be added be F\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Amount of 4% butterfat milk, plus 80 gallons of 1% milk, equals 2% of the sum of the amount of butterfat milk to be added, and 80 gallons.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "This statement, in equation form is: .04F + .01(80) = .02(F + 80)\r
