Landen Corporation uses a job-order costing system. At the beginning of the year, the company made the following estimates: During the year, Job 550 was started and completed. The following information is available with respect to this job: 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 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 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.) \begin{tabular}{|l|l|l|} \hline 1. Direct labor-hours: & & \\ \hline 1a.
