Exercise 7-14 (Algo) Calculating and Interpreting Activity-Based Costing Data [LO7-3, LO7-4] 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 activitybased costing study. The intern, in consultation with the owner, identified three major activities and then completed the rststage allocations of costs to the activity cost pools. The results appear below. Activity Cost Pool Activity Measure Total Cost Total Activity Serving a party of diners Number of parties served $ 15,340 5,900 parties Serving a diner Number of dimers served $ 117,760 12,800 diners Serving drinks Number of drinks ordered $ 30,240 10,800 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. 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 activitybased costing study, the owner knew very little about the costs of the restaurant. She knew that the total cost for the month (including organizationsustaining 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 activitybased costing system, what is the total cost and average cost per diner for serving each of the following parties of diners? (Round your intermediate calculations to 2 decimal places. Round your Total Cost final answers to 2 decimal places and your Average Cost final answers to 3 decimal places.) Total Cost Average Goat a. A party of three diners who order three drinks in total. per diner b. A party of four diners who do not order any drinks. per diner c. A party of one diner who orders four drinks. per diner
