The Seedy Vin Company produces Riesling, Charbono, and Rose wines. There are three procedures for producing each wine (the procedures for production affect the cost of the final product). One procedure allows an outside company to bottle the wine; a second allows the wine to be produced and bottled at the winery; a third allows the wine to be estate bottled. The amount of wine produced by the Seedy Vin Company by each method is shown by the matrix [ W ]. Suppose the cost for each method of production is given by the matrix [ C ]. Find the cost of producing each of the three types of wine.
