Use matrix multiplication to answer an application question
Matrices \(M\) and \(N\) describe pieces of fruit sold at school canteen counters. The columns of \(M\) and the rows of \(N\) use the same fruit type order
M: Pieces sold
Rows, in order: Main counter, Courtyard counter
Columns, in order: Apples, Bananas
\[M = \begin{bmatrix} 3 & 2 \\ 3 & 4 \end{bmatrix}\]
N: value for one unit of each fruit type
Rows, in order: Apples, Bananas
Columns, in order: Sales value
\[N = \begin{bmatrix} \$1.01 \\ \$1.87 \end{bmatrix}\]
