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: 25 & 18 & 13 \\ 6 & 20 & 17 \\ 30 & 18 & 26 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: 15 & 10 & 7 \\ 9 & 6 & 3 b) State the order of the matrix. The order of a matrix is given by the number of rows × 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 2 × 3.
