The following Information is available with respect to this job: Direct materials Direct labor cost Direct labor-hours Machine-hours $ 236 $ 371 15 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.
