Sawaya Co., Ltd., of Japan is a manufacturing company whose total factory overhead costs fluctuate considerably from year to year according to increases and decreases in the number of direct labor-hours worked in the factory. Total factory overhead costs at high and low levels of activity for recent years are given below:

Hiram’s Lakeside is a popular restaurant located on Lake Washington in Seattle. The owner of the restaurant has been trying to better understand costs at the restaurant and has hired a student intern to conduct an activity-based costing study. The intern, in consultation with the owner, identified three major activities and then completed the first-stage allocations of costs to the activity cost pools. The results appear below.

The above costs include all of the costs of the restaurant except for organization-sustaining costs such as rent, property taxes, and top-management salaries.

Some costs, such as the cost of cleaning the linens that cover the restaurant's tables, vary with the number of parties served. Other costs, such as washing plates and glasses, depend on the number of diners served or the number of drinks served.

Prior to the activity-based costing study, the owner knew very little about the costs of the restaurant. She knew that the total cost for the month (including organization-sustaining costs) was $180,000 and that 12,000 diners had been served. Therefore, the average cost per diner was $15.

Required:

1&2. According to the activity-based costing system, what is the total cost and average cost per diner for serving each of the following parties of diners?

Each unit requires 0.25 hour of direct labor.

Required:

a. Determine the direct materials price variance, direct materials quantity variance, and total direct materials cost variance. Enter a favorable variance as a negative number using a minus sign and an unfavorable variance as a positive number.

b. Determine the direct labor rate variance, direct labor time variance, and total direct labor cost variance. Enter a favorable variance as a negative number using a minus sign and an unfavorable variance as a positive number.

c. Determine the variable factory overhead controllable variance, fixed factory overhead volume variance, and total factory overhead cost variance. Enter a favorable variance as a negative number using a minus sign and an unfavorable variance as a positive number.

Magic Company makes three types of radios for small aircraft-model A, model B, and model C. The manufacturing operations are mechanized and there is no direct labor. Manufacturing overhead costs are significant, and Orlando has adopted an activity-based costing system. Direct materials costs per unit for each model are as follows:

Model A                                             $28

Model B                                             $32

Model C                                             $40

Magic Company has three activities-assembly, materials management, and testing. The cost driver for assembly is machine hours. The cost driver for materials management is number of parts, and the cost driver for testing is the number of units of product. Total costs and production volumes for the year 2012 were estimated as follows:

The Model A radio requires 12 parts to construct, and also requires 16 machine hours of processing.

The Model B radio requires 15 parts to construct, and also requires 18 machine hours of processing.

The Model C radio requires 19 parts to construct, and also requires 20.5 machine hours of processing.

Requirements:

1. Calculate the cost allocation rate for each activity.
2. Calculate the indirect cost allocated to one unit of Model A, Model B, and Model C under ABC system.
3. What is the total manufacturing cost to make one unit of Model A, Model B, and Model C under ABC system?
4. Suppose that instead of an ABC System Company has a traditional product costing system that allocates indirect costs on the basis of machine hours (total machine hours of the period are 120.000). Calculate allocation rate (round to the nearest dollar) and total manufacturing cost under traditional costing system.
