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: 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, depends on the number of diners served or the number of drinks 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 $263,200 and that 20,000 diners had been served. Therefore, the average cost per diner was $13.16 ($263,200 20,000 diners = $13.16 per diner) Required: 1. Compute the activity rates for each of the three activities. (Round your answers to 2 decimal places.) According to the activity-based costing system, what is the total cost of serving each of the following parties of diners? (Do not round intermediate calculations. Round your final answers to 2 decimal places.) a. A party of four diners who order three drinks in total. b. A party of two diners who do not order any drinks. c. A party of one diner who orders two drinks. Convert the total costs you computed in part (1) above to costs per diner. In other words, what is the average cost per diner for serving each of the following parties? (Do not round intermediate calculations. Round your final answers to 2 decimal places.) a. A party of four diners who order three drinks in total. b. A party of two diners who do not order any drinks. c. A party of one diner who orders two drinks
