L = R30, lower priced coffee
\n" ); document.write( "H = R51, higher priced coffee
\n" ); document.write( "x, how much of the higher priced coffee to use
\n" ); document.write( "M = 50 kilograms
\n" ); document.write( "M-x, quantity of lower priced coffee to use
\n" ); document.write( "T = R42.6, price of mixture\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"Hx%2BL%28M-x%29=TM\", equation to account for the cost of the mixture.\r
\n" ); document.write( "\n" ); document.write( "\"Hx%2BLM-Lx=TM\"\r
\n" ); document.write( "\n" ); document.write( "\"Hx-Lx=TM-LM\"\r
\n" ); document.write( "\n" ); document.write( "\"%28H-L%29x=TM-LM\"\r
\n" ); document.write( "\n" ); document.write( "\"highlight%28x=%28TM-LM%29%2F%28H-L%29%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Substitute the given values for M, T, H, and L. Evaluate x and M-x.\r
