1. Define and explain the meaning of a predetermined manufacturing overhead rate that is applied in a job-order costing system.
The predetermined overhead rate is used for estimating the manufacturing overhead cost because companies cannot assign the actual overhead cost to specific job. From the case, Wall Décor uses a traditional job-order costing system. The actual costs of direct materials and direct labor are charged to its specific jobs which are unframed prints, steel-framed with no matting prints, and wood-framed with matting prints.
As mentioned, predetermined overhead rate is based on estimates rather than actual results. This is because the predetermined overhead rate is computed before the period begins and is used to apply overhead cost throughout the period. Wall Décor calculates this rate as total estimated manufacturing overhead cost divided by total estimated cost of prints. Then, companies use predetermined overhead rates to allocate manufacturing overhead costs to each unframed or framed print, based on the costs of the prints. In conclusion, Wall Décor can assign this rate to a specific job to determine total cost of each specific job when it is completed.

2. What are the advantages and disadvantages of using the cost of each print as a manufacturing overhead cost driver?
From the case, Wall Décor calculates predeterminated overhead rate as total estimated manufacturing overhead cost divided by total estimated cost of prints. The advantage of using the cost of each print as a manufacturing overhead cost driver is that the base is easily to determined because we can calculate the cost of the prints.
There are some disadvantages of using the cost of each print as a manufacturing overhead cost driver. Manufacturing overhead is an indirect cost. This means that it is either impossible or difficult to trace these costs to a particular product.
