ABSTRACT OF THE DISCLOSURE The disclosure relates to a weighing and computing system for determining and displaying the total net price of a series of commodity items including items to be weighed for determining individual net prices from unit weight prices and items of fixed net prices which are not to be weighed. The system includes a weighing mechanism comprising a platform upon which a commodity item to be weighed is placed for pro- viding reference and gross weight signals corresponding to the load on the platform with the reference weight signals corresponding to the total load of all previous commodities in the series which have been weighed and the gross weight signals corresponding to the total load of all the previous commodities weighed and the load of the next commodity in the series to be weighed and a selectively operable unit price device for providing a rate signal corresponding to a unit weight price for a commodity to be weighed or an item net price signal for a commodity of fixed net price. The system also includes a computer comprising a reference weight memory device for storing reference weight signal developed by the weighing mechanism, a subtracting facility for determining the difference between the gross weight signal and the reference weight signals to provide a net weight for each commodity to be weighed, a multiplying facility responsive to the weight difference determination for multiplying each net weight by a corresponding rate signal for providing a net price for each of the weighed commodities and net price accumulating means for accumulating all of the net prices. The system further includes a display coupled to the net accumulator for displaying the sum total of the net prices. In a preferred form, the system determines a plurality of average net weights during predetermined time intervals until two consecutive average net weights are the same. At such times the system computes the net price of the commodity being weighed.
