Process Costing
Process costing is a sort of operation costing which is employed to determine the value of a product at each process or stage of producing process, applicable where goods produced from a series of continuous operations or procedure.
Job Costing
Job costing is adhesive costs of each and every job involved in the production processes. It is an accounting measure. It is a method which determines the cost of specific jobs, which are performed according to the consumer’s specifications. Job costing is possible only in businesses where the production is done as per the customer’s requirement. For example, some customers order to manufacture furniture as per their needs.
ABC Costing
Cost Accounting is a form of managerial accounting that helps the company in assessing the total variable cost so as to compute the cost of production. Cost accounting is generally used by the management so as to ensure better decision-making. In comparison to financial accounting, cost accounting has to follow a set standard ad can be used flexibly by the management as per their needs. The types of Cost Accounting include – Lean Accounting, Standard Costing, Marginal Costing and Activity Based Costing.

The amount of increase in operating income is $2,500. Since, the
operating income increases, Component K2 should be purchased.
Working Notes:
Calculation of the increase in operating income:
Increase in operating income = Number of units × Operating income per unit
= 10, 000 units x $0.25
= $2, 500
Ac
Hence, the increase in operating income is $2,500.

![Use the following information for Exercises 8-38 and 8-39:
Zion Manufacturing had always made its components in-house. However, Bryce Component
Works had recently offered to supply one component, K2, at a price of $25 each. Zion uses
10,000 units of Component K2 each year. The cost per unit of this component is as follows:
Direct materials
$12.00
Direct labor
8.25
Variable overhead
4.50
Fixed overhead
2.00
Total
$26.75
Exercise 8-38 Make-or-Buy Decision
Refer to the information for Zion Manufacturing above. The fixed overhead is an allocated ex-
pense; none of it would be eliminated if production of Component K2 stopped.
Required:
1. What are the alternatives facing Zion Manufacturing with respect to production of
Component K2?
2. List the relevant costs for each alternative. If Zion decides to purchase the component
from Bryce, by how much will operating income increase or decrease?
3. CONCEPTUAL CcONNECTION Which alternative is better?
Exercise 8-39 Make-or-Buy Decision
Refer to the information for Zion Manufacturing above. Assume that 75% of Zion
Manufacturing's fixed overhead for Component K2 would be eliminated if that component
were no longer produced.
Required:
1. CONCEPTUAL CONNECTION IfZion decides to purchase the component from Bryce,
by how much will operating income increase or decrease? Which alternative is better?
2. CONCEPTUAL CONNECTION Briefly explain how increasing or decreasing the 75%
figure affects Zion's final decision to make or purchase the component.
3. CONCEPTUAL CONNECTION By how much would the per-unit relevant fixed cost have
to decrease before Zion would be indifferent (i.e., incur the same cost) between "making"
versus "purchasing" the component? Show and briefly explain your calculations.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Febb895ae-40b4-4c3f-b212-0bba0fd50829%2F61bbe267-e8c0-4393-a5da-5a36ee22b425%2Ff1qh3vf_processed.jpeg&w=3840&q=75)
