Ramsey Company produces speakers (Model A and Model B). Both products pass through two producing departments. Model A's production is much more labor-intensive than that of Model B. Model B is also the more popular of the two speakers. The following data has been gathered for the two products:

1. Compute the overhead cost per unit for each product by using a plantwide rate based on direct labor hours. (Round to two decimal places.)
Plantwide rate: per DLH
Model A: overhead cost per unit | |
Model B: overhead cost per unit |
2. Compute the overhead cost per unit for each product by using ABC. (Round rates and unit overhead costs to two decimal places.)
Model A: overhead cost per unit | |
Model B: overhead cost per unit |

3. Suppose that Ramsey decides to use departmental overhead rates. There are two departments: Department 1: (machine intensive) with a rate of $3.40 per machine hour and Department 2: (labor intensive) with a rate of $1.00 per direct labor hour. The consumption of these two drivers is as follows:
Department 1 |
Department 2 |
|
Machine Hours |
Direct Labor Hours |
|
Model A | 10,000 | 135,000 |
Model B | 190,000 | 260,000 |
Compute the overhead cost per unit for each product by using departmental rates. (Round to two decimal places.)
Model A: per unit | |
Model B: per unit |
4. CONCEPTUAL CONNECTION Using the activity-based product costs as the standard, comment on the ability of departmental rates to improve the accuracy of product costing. Did the departmental rates do better than the plantwide rate?

A common justification is to use________ hours for machine-intensive departments and_____________ hours for labor-intensive departments. Using activity-based costs as the standard, we can say that departmental rates_____________ the accuracy of the overhead cost assignment for both products. The departmental rates cost A well_______________ the ABC method while the plantwide rate costs A well_________________ the ABC method. However, the rates of difference are very close. Looking at it this way, departments costs are not clearly more wrong than the plantwide rate; they are wrong in a _______________ direction.
