Hiram's Lakeside is a popular restaurant located on Lake Washington in Seattle. The restaurant's owner wants to better understand his costs and hired a student intern to conduct an activity-based costing study. The intern identified three activities, completed the list: stage cost allocations and gathered the activity measure data shown below. The above costs exclude organization-sustaining costs such as rent, property taxes, and top-management salaries. Sorne 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 activity-based costing study, the owner knew very little about the restaurant costs. She only knew the total cost for the month (including organization-sustaining costs) was $180,000 and 12,000 diners had been served. Therefore, the average cost per diner was $15.
