The following information is available with respect to this job Direct materials Direct labor cost Direct labor-hours Machine-hours $ 187 S 370 15 Required: 1. Assume that Landen has historically used a plantwide predetermined overhead rate with direct labor-hours as the allocation bia Under this approach: a.

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 belleves 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 Intermedlate calculatlons to 2 declmal places. Round your Predetermlned Overhead Rate answers to 2 declmal places and all other answers to the nearest whole dollar.) 1.
