Tech Solutions is a consulting firm that uses a job-order costing system. Its direct materials consist of hardware and software that it purchases and installs on behalf of its clients.

Tech Solutions is a consulting firm that uses a job-order costing system. Its direct materials consist of hardware and software that it purchases and installs on behalf of its clients. The firm's direct labor includes salaries of consultants that work at the client's job site, and its overhead consists of costs such as depreciation, utilities, and insurance related to the office headquarters as well as the office supplies that are consumed serving clients. Tech Solutions computes its predetermined overhead rate annually on the basis of direct labor-hours. At the beginning of the year, it estimated that 80,000 direct labor-hours would be required for the period's estimated level of client service. The company also estimated exist680,000 of fixed overhead cost for the coming period and variable overhead of exist0.50 per direct labor-hour. The firm's actual overhead cost for the year was exist692,000 and its actual total direct labor was 83,000 hours.
 
Required:
1. Compute the predetermined overhead rate.
2. During the year, Tech Solutions started and completed the Xavier Company engagement. The following information was available with respect to this job:

$$ \begin{array}{ll} \text { Direct materials } & \$ 38,000 \\ \text { Direct labor cost } & \$ 21,000 \\ \text { Direct labor hours worked } & 280 \\ \hline \end{array} $$

Compute the total job cost for the Xavier Company engagement.

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

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 production   150,000
Machine-hours required to support estimated production   75,000
Fixed manufacturing overhead cost $ 420,000
Variable manufacturing overhead cost per direct labor-hour $ 4.60
Variable manufacturing overhead cost per machine-hour $ 9.20
 

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

     
Direct materials $ 195
Direct labor cost $ 288
Direct labor-hours   15
Machine-hours   5
 

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.)
