\n" ); document.write( "\n" ); document.write( "\"%2830%2A3%2Bh%2A2%29%2F%2830%2Bh%29=2.50\"
\n" ); document.write( "h is the number of ounces of the $2 per ounce herbs to use. Adding h increases the amount of money of the blend only because it increases the amount of the blend. The amount h is less price than the given $3 per ounce herbs; so the unit price decreases.
