The Gilster Company, a machine tooling firm, has several plants. One plant, located in St. Cloud, Minnesota, uses a job order costing system for its batch production processes. The St. Cloud plant has two departments through which most jobs pass. Plant-wide overhead, which includes the plant manager's salary, accounting personnel, cafeteria, and human resources, is budgeted at $400,000. During the past year, actual plantwide overhead was $390,000. Each department's overhead consists primarily of depreciation and other machine-related expenses. Selected budgeted and actual data from the St. Cloud plant for the past year are as follows. Department A Department B Budgeted department overhead (excludes plantwide overhead) Actual department overhead Expected total activity: Direct labor hours Machine-hours Actual activity: Direct labor hours Machine-hours $ 100,000 120,000 $ 453,600 465,600 52,000 25,000 16,000 54,000 53,500 24,000 16,800 56,000 For the coming year, the accountants at the St. Cloud plant are in the process of helping the sales force create bids for several jobs. Projected data pertaining only to job no. 110 are as follows. Direct materials $22,000 Direct labor cost: Department A (3,000 hr) 45,000 Department B (1,100 hr) 10,800 Machine-hours projected: Department A Department B Units produced 240 1,200 8,000 Assume the St. Cloud plant uses three separate overhead rates to assign overhead costs to jobs. b-1. Find the plant wide overhead rate by using expected machine hours. b-2. Find the department overhead rate using expected machine hours for Department A and Department B. b-3. Calculate the projected manufacturing costs per unit for job 110 using the three separate rates computed in b-1 and b-2. The Gilster Company, a machine tooling firm, has several plants.
