Hirams 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 activitybased costing study. The intern identified three activities, completed the firststage cost allocations and gathered the activity measure data shown below.
Activity Cost Pool Activity Measure Total Cost Total Activity

Serving a diner Number of diners served $ diners
Serving drinks Number of drinks ordered $ drinks
The above costs exclude organizationsustaining costs such as rent, property taxes, and topmanagement 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.
