PROBLEM 2-16 Plantwide Predetermined Overhead Rates; Pricing LO2-1, LO2-2, LO2-3 Landen Corporation uses a job-order costing system. At the beginning of the year, the company made the following estimates: During the year, Job 550 was started and completed. The following information is available with respect to this job: Required: 1. Assume that Landen has historically used a plantwide predetermined overhead rate with direct labor-hours as the allocation base. Under this approach: a. Compute the plantwide predetermined overhead rate. b. Compute the total manufacturing cost of Job 550 . c. If Landen uses a markup percentage of 200% of its total manufacturing cost, what selling price would it establish for Job 550 ? 2. Assume that Landen's controller believes that machine-hours is a better allocation base than direct labor-hours. Under this approach: a. Compute the plantwide predetermined overhead rate. b. Compute the total manufacturing cost of Job 550 . c. If Landen uses a markup percentage of 200% of its total manufacturing cost, what selling price would it establish for Job 550 ? 3. Assume that Landen's controller is right about machine-hours being a more accurate overhead cost allocation base than direct labor-hours. If the company continues to use direct laborhours as its only overhead cost allocation base what implications does this have for pricing jobs such as Job 550
