Landen Corporation uses a job-order costing system. At the beginning of the year, the company made the following estimates 160,000 Direct labor-hours required to support estimated production Machine-hours required to support estimated production 80,000 $480,000 $ 5.00 Variable manufacturing overhead cost per direct labor-hour Variable manufacturing overhead cost per machine-hour 10.00 During the year, Job 550 was started and completed. The following information is available with respect to this job $240 Direct materials Direct labor $233 Direct labor hours Machine-hours 15 Required: L 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? (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) 1. Direct labor-hours: a. Predetermined overhead rate Total manufacturing cost of b ob 550 c. Selling price 2. Machine-hours: a. Predetermined overhead rate Total manufacturing cost of b ob 550 c.
