Let amount of 3.25% milkfat to be added, be T
\n" );
document.write( "Then amount of 1% milkfat to be added = 60 - T
\n" );
document.write( "We then get the following MIXTURE equation: .0325T + .01(60 - T) = .03(60)
\n" );
document.write( ".0325T + .6 - .01T = 1.8
\n" );
document.write( ".0325T - .01T = 1.8 - .6
\n" );
document.write( ".0225T = 1.2
\n" );
document.write( "T, or amount of 3.25% milkfat to be added = 
\n" );
document.write( "Amount of 1% milkfat to be added: \r
\n" );
document.write( "\n" );
document.write( "If you want a system of equations, then let the amount of 3.25% and 1% to be added, be T, and S, respectively
\n" );
document.write( "Then the system is: 
\n" );
document.write( "Solve for T, and S to get the amount of 3.25% and 1%, respectively.
\n" );
document.write( "It's that easy. Nothing COMPLEX nor CONFUSING! \n" );
