The restaurant's owner wants to better understand his costs and hired a student intern to conduct an activity-based costing study. The intern identied three activities, completed the rst- stage cost allocations and gathered the activity measure data shown below. Activity Cost Pool Activity Measure Total Cost Total Activity Serving a party of diners Number of parties served 5 33,000 6,000 parties Serving a diner Number of diners served $ 138,000 15,000 diners Serving drinks Number of drinks ordered 5 24,000 10,000 drinks The above costs exclude 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 restaurant's costs. She only knew the total cost for the month (including organization-sustaining costs) was $240,000 and 15,000 diners had been served. Therefore, the average cost per diner was $16. Required: 1 and 2.
