Here are the solutions for the matrix problems:
1. The table below shows the number of fruits sold by three vendors on a certain market day.
| Vendor | Pineapples | Oranges | Mangoes |
|---------|------------|---------|---------|
| Michael | 25 | 18 | 13 |
| Joan | 6 | 20 | 17 |
| Joy | 30 | 18 | 26 |
Represent the information as a matrix.
To represent the information as a matrix, we simply arrange the numerical values in rows and columns as they appear in the table.
The matrix is:
$$\boxed{\begin{bmatrix} 25 & 18 & 13 \\ 6 & 20 & 17 \\ 30 & 18 & 26 \end{bmatrix}}$$
2. The table below shows the number of books sold in a bookshop for two days.
| Day | Text books | Exercise books | Story books |
|-------|------------|----------------|-------------|
| Day 1 | 15 | 10 | 7 |
| Day 2 | 9 | 6 | 3 |
a) Represent the information above in matrix form.
To represent the information as a matrix, we arrange the numerical values in rows and columns.
The matrix is:
$$\boxed{\begin{bmatrix} 15 & 10 & 7 \\ 9 & 6 & 3 \end{bmatrix}}$$
b) State the order of the matrix.
The order of a matrix is given by the number of rows $\times$ the number of columns.
In the matrix from part (a):
• There are 2 rows (Day 1 and Day 2).
• There are 3 columns (Text books, Exercise books, Story books).
The order of the matrix is $\boxed{2 \times 3}$.
