Desert Industries manufactures 5,000 units of Part X300 each month for use in production. The facilities now being used to produce Part X300 have fixed monthly overhead costs of $65,000, and a theoretical capacity to produce 7,000 units per month. If Desert were to buy Part X300 from an outside supplier, the facilities would be idle and 80% of the fixed costs would continue to be incurred. There are no alternative uses for the production facilities. The variable production costs of Part X300 are $30 per unit. Fixed overhead is allocated based on planned production levels.
If Desert Industries continues to use 5,000 units of Part X300 each month, it would realize a net benefit by purchasing Part X300 from an outside supplier only if the supplier's unit price is less than what amount?
