Stan's Cookhouse is a popular restaurant located in the center of Birmingham. 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. He then completed the first-stage allocations of costs to the activity cost pools, using data from last months operations. The results appear below:

Activity Cost Pool	Activity Measure	Total Cost		Total Activity
Serving a party of diners	Number of parties served		10,000	12,000	parties
Serving a diner	Number of diners served		83,000	14,000	diners
Serving a drink	Number of drinks ordered		33,000	11,000	drinks

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. A group of diners who ask to sit at the same table are counted as a party. Some costs, such as the costs of cleaning linen, are the same whether one person is at a table or the table is full. Other costs, such as washing dishes, depend on the number of diners served.

Prior to the activity-based costing study, the owner knew very little about the costs of the restaurant. He knew that the total cost for the month (including organization-sustaining costs) was 177,000 and that 18,000 diners had been served. Therefore, the average cost per diner was 9.83.

Required:

1.	According to the activity-based costing system, what is the total cost of serving each of the following parties of diners? (Round your intermediate calculations to 2 decimal places. Round your answers to 2 decimal places.)

2.	Convert the total costs you computed in (1) above to costs per diner. In other words, what is the average cost per diner for serving each of the following parties? (Round your intermediate calculations to 2 decimal places. Round your answers to 2 decimal places.)

3.	Which of the following are the reasons for that the average cost per diner under ABC differs from the overall average cost of 9.83 per diner? (You may select more than one answer.
