Precision Manufacturing Incorporated (PMI) makes two types of industrial component parts-the EX300 and the TX500. It annually produces 63,000 units of EX300 and 12,800 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. Additional information relating to the company's two product lines is shown below: Direct materials Direct labor EX300 TX500 $ 369,325 $ 123,000 $ 165,550 $ 44,000 Total $ 534,875 $ 167,000 es The company is considering implementing an activity-based costing system that distributes all of its manufacturing overhead to four activities as shown below. Activity Cost 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 $ 227,650 180,600 91,080 68,470 $ 567,800 EX300 93,000 90 Activity TX500 64,000 330 1 1 Total 157,000 420 2 $ 123,000 $ 44,000 $ 167,000 Required: 1-a.
