The sales of certain products in three cities are given in the 4 by 3 matrix below. City 1 City 2 46 City 3 32 Tablets 71 Laptop Computers 50 53 66 Cell Phones 31 78 68 Personal DVR 42 37 61 The cost of the items depend if they were sold "Retail" or "Wholesale". The Retail costs were: $185 for tablets, $344 for laptops, $310 for cell phones, and $1,155 for DVRS. The Wholesale costs were: $327 for tablets, $467 for laptops, $241 for cell phones, and $1,155 for DVRS. To get the total revenue at each city for Retail and Wholesale, we would need to put the information above rows and (on retail and wholesale costs) into a matrix that has columns and multiply it by the 4 by 3 matrix on sales at each city for each item. rows and After multiplying these two matrices, we would have a matrix that has columns. and column The total wholesale revenue from city 2 would be in row
