Problem 2-18 (Static) Plantwide Predetermined Overhead Rates; Pricing [LO2-1, LO2-2, LO2-3] Landen Corporation uses job-order costing. At the beginning of the year, it made the following estimates: During the year, Job 550 was started and completed. The following information pertains to this job: Required: 1. Assume 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 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 ? Note: Round your intermediate calculations to 2 decimal places. Round your Predetermined Overhead Rate answers to 2 decimal places and all other answers to the nearest whole dollar
