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

Direct labor-hours required to support estimated production 65,000

Machine-hours required to support estimated production 32,500

Fixed manufacturing overhead cost $ 195,000

Variable manufacturing overhead cost per direct labor-hour $ 1.20

Variable manufacturing overhead cost per machine-hour $ 2.40

During the year, Job 550 was started and completed. The following information pertains to this job:

Direct materials $ 250

Direct labor cost $ 318

Direct labor-hours 15

Machine-hours 5

1. Assume 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 Landens 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?

Note: 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.

1. Direct labor hours:

1a. Predetermined overhead rate per DLH?

1b. Total manufacturing cost of Job 550?

1c. Selling price?

2. Machine hours:

2a. Predetermined overhead rate per MH?

2b. Total manufacturing cost of Job 550?

2c. Selling price?

To whomever decides to help me with this homework problem, thank you.
