Last thing i need to graduate a home furnishings store has two locations, one in the north and one in the south. the matrices below show the costs of their most popular sheet set, in dollars, and the current inventory of the sets in two colors at both locations. find cn and cs. tell which location has the greater dollar value of beige sheets in their inventory, and find the difference in these dollar values. find cn + cs. describe what each element in the matrix represents.

For a), wouldn't you multiply the cost of a twin by the quantity of a twin beige (N) and the cost of a queen by the quantity of the queen beige (N) and then the cost of the king by the quantity of the king beige (N) for CN and do the same thing but with the south quantities? 
And then for b), it's just comparing which one had the most money and find the difference... 
And then C), would be relatively self explanatory where CN would be the potential profit in N and CS would be the potential profit in S and then CN+CS would be the potential profit total?
