Problem 4-12 (Algo) Contrasting ABC and Conventional Product Cost [LO4-2, L04-3, LO4-4) Precision Manufacturing Incorporated (PMI) makes two types of industrial component parts--the EX300 and the TX500. It annually produces 51,000 units of EX300 and 11,600 units of TX500. The company's conventional cost system allocates manufacturing overhead to products using a plantwide overhead rate and direct labor dollars as the allocation base. Additiona information relating to the company's two product lines is shown below: EX300 TX500 Total Direct materials $ 357,325 $ 153,550 $ 510,875 Direct labor $ 111,000 $ 38,000 $ 149,000 The company is considering implementing an activity-based costing system that distributes all of its manufacturing overhead four activities as shown below: Activity Coot Pool (and Activity Measure) Machining machine-hours) Setups (setup hours) Product-level (number of products) General factory (direct labor dollars) Total manufacturing overhead cost Manufacturing Overhead $ 152,900 74,400 76,660 38,40 $ 342,700 EX300 81,000 30 1 $ 111,000 Activity TX500 58,000 210 1 $ 38,000 139,000 240 2 $ 149,000 Required: 1-a. Compute the plantwide overhead rate that would be used in the company's conventional cost system 1-b. Using the plantwide rate, compute the unit product cost for each product. 2-a. Compute the activity rate for each activity cost pool. 2-b. Using the activity rates, compute the unit product cost for each product
