\n" ); document.write( "H=70%
\n" ); document.write( "T=30%
\n" ); document.write( "u=UNKNOWN amount for L material
\n" ); document.write( "v=300 oz. for H material\r

\n" ); document.write( " $\"highlight%28%28uL%2BvH%29%2F%28u%2Bv%29=T%29\"$
\n" ); document.write( "Solve for u, the only unknown variable.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Suitable steps should follow, and be equivalent to formula:
\n" ); document.write( " $\"highlight%28u=v%28H-T%29%2F%28T-L%29%29\"$ .\r
