You could use a 'calc' element, which returns something like:

return (int)'{yourtable___amount}' * (float)'{yourtable___price}';

Substitute your element full names as appropriate.

If you haven't done so already, you'll probably need to do a full github update, then discover and publish the calc element plugin in J!'s extension manager.
