Generally speaking, the profit is still quite good. Before we can understand this problem, we must first understand the cost composition of cold rice noodles. At present, the single portion of cold rice noodles sold in the market is basically about five taels, so the production cost of cold rice noodles with this amount is less than fifty cents (including flour, coal and brush oil), and the seasoning cost is one piece per serving, at most one piece and two pieces, including Chili oil, sesame oil, garlic juice, seasoning water, vinegar and shredded cucumber. The comprehensive cost of a cold noodle is at most 1.7 yuan, no matter where it is, and no matter how much the retail price of cold noodle is, the cost will not exceed this range. For example, if the local retail price is 5 yuan, it will sell an average of 50 copies a day, and the monthly net income will reach 5,000. If it sells an average of 100 copies a day, the monthly net income will reach 10,000. Of course, the higher the selling price, the greater the selling volume, and the more you will earn.
