The Blade Division of Dana Company produces hardened steel blades. Approximately one-third of the Blade Division's output is sold to the Lawn Products Division of Dana; the remainder is sold to outside customers. Blade Division's estimated sales and cost data for the year ending June 30^th are as follows:

	Sales to Lawn Products Division				Sales to Outsiders
Revenue	$	31,500			$	84,000
Variable costs		21,000				42,000
Fixed costs		6,000				28,500
Gross margin	$	4,500			$	13,500
Unit sales		21,000				42,000

The Lawn Products Division has an opportunity to purchase, on a continual basis, 10,000 blades (of identical quality) from an outside supplier, at a cost of $1.50 per unit. Assume that the Blade Division cannot sell any additional products to outside customers. Assume, too, that there are no short-term avoidable fixed costs. Based solely on short-term financial considerations, should Dana allow its Lawn Products Division to purchase the blades from the outside supplier, and why?
