A bag of flour can make 240 cold noodles, and the production cost of each cold noodle is as high as 55 cents. The seasoning fee includes one piece of Chili oil, one piece of sesame sauce, one piece of seasoning water, one piece of garlic juice, one piece of vinegar and one piece of shredded cucumber. The tallest piece is two pieces, and one piece is a bowl. At present, the retail price of cold noodles is also the lowest five yuan, and six or seven yuan at night is very common. You can calculate the specific profit according to the local selling price. Generally speaking, even for mobile stalls, under normal circumstances, the daily sales volume can be stabilized at more than 100, which is the most conservative figure.
