An Engineering workshop allocates its staff into four categories: Designer, Joiner. Painter and Assembler. It is estimated that the time spent on their main products in hours are as follows: Product I Product 2 Product 3 Designer 6 4 2 Joiner 4 3 Painter 2 2 2 Assembler l 4 3 The wages. pension contribution and overheads in dollars per hour are known to be: Designer .Ioiner Painter Assembler Wages 1D 1 [l 22 21 Pensions 3 4 3 2 lUserheads l [I (I l i] Represent the above information on time spent {matrix T) and cost (matrix C} on each product {Product 11 Product 2, Product 3] as two matrices.
