Doreen Design Inc. manufactures custom-made furniture. Doreen currently uses a single overhead rate (traditional method) based on machine hours to allocate manufacturing overhead ( MOH) to individual jobs. It estimates to incur 3,000 machine hours this year and expects manufacturing overhead to be $96,000. However, the owner and CEO is considering using activity -based costing to allocate manufacturing overhead. She has identified four activities that incur or drive manufacturing overhead costs: purchase orders, parts administration, machine-set ups and machining. The budgeted activity costs for the upcoming year and the allocation bases are as follows: Job 420 used 5 purchase orders, 250 parts, 3 set-ups and 130 machine hours Job 510 used 10 purchase orders, 400 parts, 8 set-ups and 200 machine hours Required: Job 510 used 10 purchase orders, 400 parts, 8 set-ups and 200 machine hours Required: 1.
