Laden 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 production 140.000

Machine-hours required to support estimated production 70,000

Fixed manufacturing overhead cost $784,000

Variable manufacturing overhead cost per direct labor-hour $2.00

Variable 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 $175

Direct labor cost $225

Direct labor-hours 15

Machine hours 5

Required:

1. Assume that Landen has historically used a 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 calculation to 2 decimal places. Round your predetermined overhead Rate answers to 2 decimal places and all other answers to the nearest whole dollar.)
