H=16

\n" ); document.write( "L=12
\n" ); document.write( "M=5
\n" ); document.write( "u = how much of the L priced cheese
\n" ); document.write( "v = how much of the H priced cheese\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"u%2Bv=M\"$
\n" ); document.write( "and
\n" ); document.write( " $\"%28Lu%2BHv%29%2FM=T\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "That is a system of equations in the unknown variables, u and v.
\n" ); document.write( "Solve the system for u and v, and you will have essentially solved any two part mixture problem which fits this form. This is like a concentration-mixture problem, but here, the concentration is as DOLLARS PER KILOGRAM. Think of the cheeses as containing dollars. \n" ); document.write( "
