A dairy keeps two kinds of milk on hand, skim milk has 0.2% butterfat and whole milk has 3.4% butterfat.
\n" ); document.write( " How many gallons of each type of milk does a company need to produce 220 gallons of 1% milk for a grocery store?
\n" ); document.write( ":
\n" ); document.write( "let x = amt of 3.4% milk
\n" ); document.write( "the total is to be 220 gal, therefore
\n" ); document.write( "(220-x) = amt of .2% milk
\n" ); document.write( ":
\n" ); document.write( "The amt of butterfat equation
\n" ); document.write( ".034x + .002(220-x) = .01(220)
\n" ); document.write( ".034x + .44 - .002x = 2.20
\n" ); document.write( ".034x - .002x = 2.20 - .44
\n" ); document.write( ".032x = 1.76
\n" ); document.write( "x = 1.76/.032
\n" ); document.write( "x = 55 Gal of 3.4% mile required
\n" ); document.write( "then
\n" ); document.write( "220 - 55 = 165 gal of .2% required
\n" ); document.write( " \n" ); document.write( "
\n" );
