Direct labor-hours required to support estimated production 65,000 Machine-hours required to support estimated production 32,500 Fixed manufacturing overhead cost $ 195,000 Variable manufacturing overhead cost per direct labor-hour $ 1.20 Variable manufacturing overhead cost per machine-hour $ 2.40 During the year, Job 550 was started and completed. The following information is available with respect to this job: Direct materials $ 250 Direct labor cost $ 318 Direct labor- 15 hours Machine-hours 5 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? (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.) per DLH 1.
