The fastener division of Southern Fasteners manufactures zippers and then sells them to customers for $8 per unit. Its variable cost is $3 per unit, and its fixed cost per unit is $1.50. Management would like the fastener division to transfer 12,000 of these zippers to another division within the company at a price of $3. The fastener division could avoid $0.20 per zipper of variable packaging costs by selling internally.
