Manhattan's Electronic Assembly Division wants to purchase 5,500 circuit boards either internally or else use a similar board in the marketplace that sells for $47. The Electronic Assembly Division's management feels that if the first alternative is pursued, a price concession is justified, given that both divisions are part of the same firm.
