Soft Cushion Company is highly decentralized. Each division is empowered to make its own sales decisions. The Assembly Division can purchase cushion stuffing from the Production Division or from external suppliers. The Production Division has been the major supplier of stuffing in recent years. The Assembly Division has announced that two external suppliers will be used to purchase the stuffing at$20 per kilogram for the next year. The Production Division recently increased its unit price to$40. The manager of the Production Division presented the followinginformation; variable cost$32, fixed cost$8, to top management in order to attempt to force the Assembly Division to purchase the stuffing internally. The Assembly Division purchases20,000 kg per month.

What would be the monthly operating advantage(disadvantage) of purchasing the goods internally assuming the external supplier increased its price to$50 per kilogram and the Production Division is able to utilize facilities for otheroperations, resulting in a monthly cashoperating savings of$30 perkilogram?
