Gino's Restaurant is a popular restaurant in Boston, Massachusetts. 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: A group of diners who ask to sit at the same table is counted as a party. Some costs, such as the costs of cleaning linen, are the same whether one person is at a table or the table is full. Other costs, such as washing dishes, depend on the number of diners served. Data concerning these activities are shown below: Prior to the activity-based costing study, the owner knew very little about the costs of the restaurant. She knew that the total cost for the month was $175,000 and that 10,000 diners had been served. Therefore, the average cost per diner was $17,50 ( $175,000 10,000 diners =$17,50 per diner)
