Humber Products manufactures its products in two separate departments: milling and assembly. Total manufacturing overhead costs for the year are budgeted at $2 million. Of this amount Milling Department incurs $1,200,000 (primarily for machine operation and depreciation) while the Assembly Department incurs $800,000. Humber Products estimates that it will incur 8,000 machine hours (all in the Milling Department) and 25,000 direct labour hours (5,000 in the Milling Department and 20,000 in the Assembly Department) during the year Humber Products currently uses a plantwide overhead rate based on direct labour hours to allocate overhead. However, the company is considering refining its overhead allocation system by using departmental overhead rates. The Milling Department would allocate its overhead using machine hours (MH), but the Assembly Department would allocate its overhead using direct labour (DL) hours. The following chart shows the machine hours (MH) and direct labour (DL) hours incurred by Jobs 600 and 601 in each production department: Milling Department 4 DL hours 6 machine hours Assembly Department 12 DL hours Job 600 Job 601 4 DL hours 12 machine hours 12 DL hours Both Jobs 600 and 601 used $2,000 of direct materials. Wages and benefits total $25 per direct labour hour Humber Products prices its products at 110% of total manufacturing costs. 1. Compute Humber Products' current plantwide overhead rate. 2. Compute refined departmental overhead rates. 3. Compute the total amount of overhead allocated to each job if Humber Products uses its current plantwide overhead rate
