How to modify my jQuery script to add a math function and pass the result?
<p>You can find my jQuery in this fiddle <a href="http://jsfiddle.net/qSkZW/9/" rel="nofollow">http://jsfiddle.net/qSkZW/9/</a> where the value changes based on your dropdown selection.</p>

<p>What I need is to multiply the selected quantity with a PHP variable. For example when<code>$price = '10';</code> and you select 3 for quantity, you get an output of 30.</p>

<p>Also, how can I pass the result to display it in the next page ?</p>

<p>Thank you.</p>

<p>What I am trying to clone is the <strong>Your Purchase</strong> system found here <a href="https://www.groupon.com/deals/pizza-delight/confirmation?ms=false&amp;pledge_id=538463" rel="nofollow">https://www.groupon.com/deals/pizza-delight/confirmation?ms=false&amp;pledge_id=538463</a> that you add the quantity and you get the final price.</p>
