The Lynn Company uses a normal job-costing system at its Minneapolis plant. The plant has a machining department and an assembly department. Its job-costing system has two direct-cost categories (direct materials and direct manufacturing labor) and two manufacturing overhead cost pools (the machining department overhead, allocated to jobs based on actual machine-hours, and the assembly department overhead, allocated to jobs based on actual direct manufacturing labor costs). The 2011 budget for the plant is as follows:

Required:
1. Present an overview diagram of Lynn’s job-costing system. Compute the budgeted manufacturing over head rate for each department.
2. During February, the job-cost record for Job 494 contained the following:




Compute the total manufacturing over head costs allocated to Job 494.
3. At the end of 2011, the actual manufacturing overhead costs were $2,100,000 in machining and $3,700,000 in assembly. Assume that 55,000 actual machine-hours were used in machining and that actual direct manufacturing labor costs in assembly were $2,200,000. Compute the over- or under allocated manufacturing overhead for each department.
