Problem 4-12 Contrasting ABC and Conventional Product Cost (LO4-2, L04-3, L04-4) Precision Manufacturing Inc. (PMI) makes two types of industrial component parts--the EX300 and the TX500 any produces 68,000 units of EX300 and 13,300 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.
