Construct matrix A for 2019 sales.

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).
