3. Hiram's Lakeside is a popular restaurant located on Lake George in Manitoba. 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: Activity cost pool Activity measure Serving a party of diners Number of parties served Serving a diner Number of diners served Serving drinks Number of drinks served 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 the linen, are the same whether one person is at a table or the table if full. Other costs, such as washing dishes, depend on the number of diners served. Data concerning last month's operations are displayed below. The intern has already completed the allocation of overhead costs to the activity cost pools. Serving a party Serving a diner Serving a drink Total cost S000 5138.000 12000 Total activity 6,000 parties 15,000 diners 10.000 drinks : The above costs include all of the costs of the restaurant sccept for organization- sustaining costs such as rent, property taxes, and top-management salaries Prior to the activity-based costing study, the owner knew very little about the costs of the restaurant.
