Answer:
The companies would adopt costing system as shown below:
Warner Bros.Motion Pictures-Job order
Jif Peanut Butter-Process Costing
Hill Country Medical Practice-Job order
Kraft, Inc-Process Costing
Explanation:
Process costing is a cost accounting approach for gathering and assigning manufacturing costs to quantity produced.It is typically suitable where there is mass production.Since Kraft and Jif Peanut Butter produce food items in mass,process costing fits perfectly.
Job order costing on the other hand,is most appropriate when products or services are tailored to customer's request ,each with its unique features,hence unique cost structure.The movies produced by Warner Bros,Motion Pictures share the unique nature, so also a medical practice would have to handle surgeries that are not exactly similar.
