The sales of certain products in three cities are given in the 4 by 3 matrix below. City 1 City 2 City 3

Tablets 61 68 37

Laptop Computers 51 66 39

Cell Phones 58 77 65

Personal DVR 38 76 40

The cost of the items depend if they were sold "Retail" or "Wholesale". The Retail costs were: $182 for tablets, $301 for laptops, $434 for cell phones, and $1,657 for DVRs. The Wholesale costs were: $349 for tablets, $425 for laptops, $161 for cell phones, and $1,657 for DVRs. To get the total revenue at each city for Retail and Wholesale, we would need to put the information above (on retail and wholesale costs) into a matrix that has rows and columns and multiply it by the 4 by 3 matrix on sales at each city for each item. After multiplying these two matrices, we would have a matrix that has rows and columns. The total wholesale revenue from city 2 would be in row and column

TThe math is solved on the white papers. The second page is a continuation of the calculation. However, W and R in the above some represent wholesale and retail costs, respectively.
