Landen Corporation uses a job-order costing system. At the beginning of the year, the company made the following estimates:

Direct labor-hours required to support estimated production140,000Machine-hours required to support estimated production70,000Fixed manufacturing overhead cost$784,000Variable manufacturing overhead cost per direct labor-hour$2.00Variable manufacturing overhead cost per machine-hour$4.00

During the year, Job 550 was started and completed. The following information is available with respect to this job:

Direct materials$175Direct labor cost$225Direct labor-hours15Machine-hours5

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?
