5. Nanook Corporation uses a normal job-costing system. The plant has a machining department and an assembly department. Its job costing system has two manufacturing overhead cost pools the machining department overhead, allocated based on machine hours, and the assembly department overhead, allocated based on direct labor costs. The budget for the coming is year is below Machining Department Assembly Department Overhead $200,000 5500,000 Direct labor costs $175,000 S400.000 Direct labor hours 12,000 22.000 Machine hours 25.000 55,000 Required: (8 points) a During the past month, the job cost sheet for job 123 had the following information Compute the amount of overhead allocated to job 123 Machining Department Assembly Department Direct materials used $18,000 $45,000 Direct labor costs $12.000 $32.000 Direct labor hours 700 925 Machine hours 1.100 800 b. Compute the total cost of job 123. c. At the end of the year, actual manufacturing overhead costs were $220,000 in machining and $522,000 in assembly. Assume that 28,000 actual machine hours were used in machining and that actual direct labor costs in assembly were $415,000. Compute the under-or overallocated manufacturing overhead for each department
