Here is the menu, fill in the Number of units to purchase in the far right column. Show work on back page to justify answer. The last problem set (PS 6), will use these units to calculate the food cost percentage for each item based on the revenue generated for the catering event. Here is the menu: Item Shrimp cocktail Amount/Serving 6-21/25* pcs (21/25 tells you that each pound of ship will have 21-25 pieces, use 23 as yield) Purchase Units case = 4 - 2.5 lb bags IQF shrimp pieces Prime rib 7 oz. rib eye AS 12 pound roasts, 34% waste Rice Pilaf 4 oz cooked case =6-2.5 lb boxes; 34-4 oz portions in each box Gr. Bean Almandine 3 oz. whole after cooking frozen case = 12; 2.5 lb bags Champagne** 2; 3oz glasses case = 12 bottles * 21/25 refers to a large size as well as a count per pound ** a bottle is a fifth of a gallon (128oz/5=25.6oz/6=4.3serv per bottle) Unit(s) Needed Food Cost Percent for Event Meal The food cost percent is a very common calculation that describes how much of ones sales, costs or revenue go for the cost of food. Here are some examples: RECALL THIS INFORMATION ABOUT FC% Budget for a hospital: Total monthly food costs: $30,000 Total monthly budget $150,000 Food cost = 30,000/150,000 = 0.20 or 20% FC% This method is similar to the one that would be used for an operation with sales, where total food costs are divided into total sales for a given time period, like a month or year. Revenue for a catered event Total Revenue ($25 ticket/meal) for 250 guests =$6250 Food cost = $2350 (food cost)/$ 6250 (revenue from event tickets) Total Food Expenditure for 250 guests = $2350 = 0.376 or 38% Menu Item and Selling Prices Ingredient cost to make one serving of lasagna = $2.17 Food cost = 2.17/6.00 Selling price for one serving of lasagna= $6.00 =0.361 or 36%
