Edwards Inc. manufactures electronics. It consists of several divisions operating as profit SBUs. Division A desires to purchase materials from Division B at a price of $85 per unit. Division B can produce 25,000 units at full capacity, and is currently operating at 90% capacity, selling only to outside customers at a variable cost of $80 per unit. B's customers pay $115 per unit. Division A pays an outsourced company $110 per unit. If purchased form Division B, B's variable costs would be $10 less because it saves on marketing expenses. Division A requires 10,000 units.

Required:

How would Division B selling to Division A affect Division A's purchasing costs? How would it affect Division B? What solution would be best for Edwards Inc., assuming Division B has the ability to operate at full capacity?
