The sales of certain products in three cities are given in the 4 by 3 matrix below. City 1 City 2 City 3 Tablets 65 55 76 Laptop Computers 49 66 71 Cell Phones 31 58 45 Personal DVR 62 72 48 The cost of the items depend if they were sold "Retail" or "Wholesale". The Retail costs were: $193 for tablets, $381 for laptops, $395 for cell phones, and $1,355 for DVRS. The Wholesale costs were: $322 for tablets, $453 for laptops, $211 for cell phones, and $1,355 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. 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
