Part A -

Gino's Restaurant is a popular restaurant in Boston, Massachusetts. 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 the following major activities:

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, depends on the number of diners served or the number of drinks served.

Data concerning these activities are shown below.

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 was $313,600 and that 32,000 diners had been served. Therefore, the average cost per diner was $9.80 ($313,600 ÷ 32,000 diners = $9.80 per diner).

Required:

1. Compute the activity rates for each of the three activities.

2. According to the activity-based costing system, what is the total cost of serving each of the following parties of diners? (Do not round intermediate calculations. Round your final answers to 2 decimal places.)

a. A party of four diners who order three drinks in total.

b. A party of two diners who do not order any drinks.

c. A party of one diner who orders two drinks.

3. Convert the total costs you computed in part (1) above to costs per diner. In other words, what is the average cost per diner for serving each of the following parties? (Do not round intermediate calculations. Round your final answers to 2 decimal places.)

a. A party of four diners who order three drinks in total.

b. A party of two diners who do not order any drinks.

c. A party of one diner who orders two drinks.

Part B -

Marine, Inc., manufactures a product that is available in both a flexible and a rigid model. The company has made the rigid model for years; the flexible model was introduced several years ago to tap a new segment of the market. Since introduction of the flexible model, the company's profits have steadily declined, and management has become concerned about the accuracy of its costing system. Sales of the flexible model have been increasing rapidly.

Overhead is applied to products on the basis of direct labor-hours. At the beginning of the current year, management estimated that $600,000 in overhead costs would be incurred and the company would produce and sell 1,000 units of the flexible model and 10,000 units of the rigid model. The flexible model requires 2.0 hours of direct labor time per unit, and the rigid model requires 1.0 hours. Direct materials and labor costs per unit are given below:

Required:

1. Compute the predetermined overhead rate using direct labor-hours as the basis for allocating overhead costs to products.

2. An intern suggested that the company use activity-based costing to cost its products. A team was formed to investigate this idea. It came back with the recommendation that four activity cost pools be used. These cost pools and their associated activities are listed as follows:

Compute the activity rate for each of the activity cost pools.

3. Using activity-based costing, do the following:

a. Determine the total amount of overhead that would be assigned to each model for the year.

b. Compute the unit product cost for one unit of each model.
