She also follows the USAR recommendation and thus separately calculates her product costs for food, beverages, and her overall cost of sales. Help Belinda complete this portion of her monthly operating records by calculating her total cost of sales and all of her cost of sales percentages for the month. Roasted Pepper: Sales and Cost of Sales This Month Percent SALES Food $ 90,000 75% Beverages 30,000 25% Total Sales $120,000 100% COST OF SALES Food Beverages Total Cost of Sales $25,200 6,600 Could Herman have computed this figure if he had not taken a physical inventory on April 30th?
