For example, the gross profit of dishes with the brand of string eating and string drinking hotpot is about 60%-70%. Let's briefly talk about the calculation method of an example:

Multiply the string number of a catty of vegetables by the unit price, and then subtract the cost of a catty of vegetables, which is equal to the gross profit. For example, the cost of a kilo of beef in 35 yuan is 180, and the unit price is 0.4 yuan, which means: 180*0.4-35=37 yuan, and 37 yuan is the gross profit of a kilo of beef.
