Manor, Inc. currently manufactures 1,000 subcomponents per month in one of its factories. The unit costs to produce the subcomponents are:

	Per unit
Direct materials		$	61
Direct labor			167
Variable manufacturing overhead			93
Fixed manufacturing overhead			122
Total unit cost		$	443

Manor is considering purchasing the subcomponents from an outside supplier, who normally charges $351 per unit. The supplier also has an "Exclusive Buyer's Club" which costs $30,000 per month to join, but whose members can purchase the subcomponents for $301 per unit. Fixed overhead is not avoidable. How many units would Manor need to order per month to make it worth it to join the "Exclusive Buyer's Club"?
