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 manufactuting cost of Job 550 . c. If Landen uses a markup percentage of 200% of its total manufactuting 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 tate. 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 intermediote calculations to 2 decimal ploces. Round your Predetermined Overhead Rote answers to 2 decimal ploces and all other answers to the nearest whole dollar.) \begin{tabular}{|l|l|l|} \hline 1.
