The reporter noticed that the plates used in this store have been unified into green plates. After weighing a number of green plates at random, it is found that most plates are actually 380 g, and some plates have errors in weight, but they are all less than 380 g. After selecting dishes, consumers need to weigh the plates and dishes to calculate the price. The weighing scale has been processed with an initial value of -395g. In other words, when a consumer weighs a dish, the calculated weight is the weight of the plate. If consumers need rice, drinks and soup, they need to pay 3 yuan more for the price of vegetables.
