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 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.) \begin{tabular}{|l|l|l|l|} \hline & \multicolumn{2}{|l|}{} & \multicolumn{2}{l|}{} \\ \hline 1. & Direct labor-hours: & per DLH \\ \hline a. & Predetermined overhead rate & \\ \hline b. & Total manufacturing cost of Job 550 & \\ \hline c. & Selling price & per MH \\ \hline 2. & Machine-hours: & \\ \hline a. & Predetermined overhead rate & \\ \hline b. & Total manufacturing cost of Job 550 & \\ \hline c. & Selling price & & \\ \hline \end{tabular}
