Landen Corporation uses job-order costing. At the beginning of the year, it made the following estimates: Direct labor-hours required to support estimated production Machine-hours required to support estimated production Fixed manufacturing overhead cost Variable manufacturing overhead cost per direct labor-hour Variable manufacturing overhead cost per machine-hour 140,000 70,000 $ 784,000 $ 2.00 $ 4.00 During the year, Job 550 was started and completed. The following information pertains to this job: Direct materials $ 175 Direct labor cost Direct labor-hours $ 225 15 5 Machine-hours 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.
