The following information was collected from the accounting records and production data for the year ending December 31, 2022, 1.7.900 units of CISCO were produced in the Machining Department 2 Variable manufacturing costs applicable to the production of each CISCO unit were: direct materials $4.57. direct labor 54.22. indirect labor $0.46, utilities $0.43 3. Fixed manufacturing costs applicable to the production of CISCO were: Cost Item Direct Total Allocated 3910 Depreciation $2,100 $3,010 Property taxes 560 370 930 Insurance 910 580 1,490 $3.570 $1.860 5.430 All variable manufacturing and direct fixed costs will be eliminated i CISCO is purchased. Allocated costs will not be eliminated if CISCO is purchased. So if CISCO is purchased the fixed manufacturing costs allocated to CISCO will have to be absorbed by other production departments 4.
