it's very simple. I'll tell you a stupid method. You can calculate the total number of semi-finished products you pickled, and then divide them into proportions. It's even worse than you developed six semi-finished meats and used them in general, so it's 1/2. You can then calculate the costs of these raw materials and other aspects that need to be developed. And then calculate it. Divide into two parts. One is the price of semi-finished products you use, and the other is the price you don't use. You can also calculate your profit.
