How many ounces,u of a nameOfMetal alloy that costs $L per ounce should be mixed with v ounces that costs $H per ounce to make a new M ounce alloy that costs $T per ounce? \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "This is the same general mixture problem like so many others of the same form.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"highlight%28%28Lu%2BHv%29%2FM=T%29\" and \"highlight%28u%2Bv=M%29\"\r
\n" ); document.write( "\n" ); document.write( "Solve this system for u and v.\r
\n" ); document.write( "\n" ); document.write( "\"Lu%2BHv=TM\" and from the material balance v=M-u so substitute.
\n" ); document.write( "\"Lu%2BH%28M-u%29=TM\"
\n" ); document.write( "\"Lu%2BHM-Hu=TM\"
\n" ); document.write( "\"Lu-Hu=TM-HM\"
\n" ); document.write( "Multiply both sides by negative 1.
\n" ); document.write( "\"Hu-Lu=HM-TM\"
\n" ); document.write( "\"u%28H-L%29=%28H-T%29%2FM\"
\n" ); document.write( "\"highlight%28u=M%28H-T%29%2F%28H-L%29%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "and continuation to solve for v will use similar skills.
\n" ); document.write( "
\n" );
