Your company has recently developed capabilities to produce a new model of frying pans with a revolutionary non-stick coating, called the PanX. Your company is currently producing at capacity. The marketing department has provided you with the following information about the per-unit demand for the PanX:

Price	Quantity	Revenue
$28	0	$0
$27	1	$27
$26	2	$52
$25	3	$75
$24	4	$96
$23	5	$115
$22	6	$132
$21	7	$147

If you dedicated all resources to the production of one good, you can produce up to 40 PanX or 20 Standard Pans. PanX costs $19.50 to produce. Standard pans can be sold for $20 and cost $14 to produce. How many units of PanX should you produce to profit maximize?

Hint: Costs to produce are variable costs. For simplicity, assume you can sell fractional units of the Standard Pan (e.g. you can sell 0.5 of a pan)
