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 seling 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 5507 (Round your intermediate calculations to 2 decimal places. Round your Predetermined Overhead Rate answers to 2 decimal splaces and all other answers to the nearest whole dollar.) 1 Direct labor-hours: aPredetermined overhead rate 4.60 per DLH Total manufacturing cost of Job 550 eSelling price overhead rate 9.20 per MH bTotal manufacturing cost of Job 550 Selling price Required: 1.
