\"C%28x%29+=+2x%5E2+%96+40x+%2B+250+\"
\n" ); document.write( "if the cost is minimized, then it will equal zero:
\n" ); document.write( "\"0+=+2x%5E2+%96+40x+%2B+250+\"
\n" ); document.write( "divide both sides by 2:
\n" ); document.write( "\"0=x%5E2-20x%2B125\"
\n" ); document.write( "factor:
\n" ); document.write( "\"%28x%2B5%29%28x-25%29\"
\n" ); document.write( "x=-5 or 25
\n" ); document.write( "since we are talking about producing an item, we cannot produce negative items, so we can discard the -5 answer.\r
\n" ); document.write( "\n" ); document.write( "costs will be minimized if 25 units or more are produced.
\n" ); document.write( "
