Here are the solutions to the matrix problems. a) Construct two matrices A and B to represent sales data for 2019 and 2020. Step 1: Construct matrix A for 2019 sales. The rows represent the dealers (Beforeward, Ramza motors Ltd) and the columns represent the car sizes (Small, Medium, Large). $$ A = \begin{bmatrix} 24 & 32 & 11 \\ 32 & 34 & 9 \end{bmatrix} $$ Step 2: Construct matrix B for 2020 sales. The rows represent the dealers (Beforeward, Ramza motors Ltd) and the columns represent the car sizes (Small, Medium, Large). $$ B = \begin{bmatrix} 26 & 38 & 16 \\ 35 & 41 & 12 \end{bmatrix}
