The management of Riverbed Manufacturing Company is trying to decide whether to continue manufacturing a part or to buy it from an outside supplier. The part, called CISCO, is a component of the company's finished product.

The following information was collected from the accounting records and production data for the year ending December 31, 2017.

1. 8,000 units of CISCO were produced in the Machining Department.

2. Variable manufacturing costs applicable to the production of each CISCO unit were:

direct materials $5.10, direct labor $4.88, indirect labor $0.45, utilities $0.44.

3. Fixed manufacturing costs applicable to the production of CISCO were:

Cost Item Direct Allocated

Depreciation $1,900 $920

Property taxes 490 420

Insurance 890 620

$3,280 $1,960

All variable manufacturing and direct fixed costs will be eliminated if CISCO is purchased. Allocated costs will have to be absorbed by other production departments.

4. The lowest quotation for 8,000 CISCO units from a supplier is $87,390.

5. If CISCO units are purchased, freight and inspection costs would be $0.34 per unit, and receiving costs totaling $1,310 per year would be incurred by the Machining Department.
