According to the example, the cost would then be: $\begin{bmatrix} 14&30&18\\ 16&25&20 \end{bmatrix}\begin{bmatrix} 75\\ 1\\ 45 \end{bmatrix}=\begin{bmatrix} 14\cdot75+30\cdot1+18\cdot45\\ 16\cdot75+25\cdot1+20\cdot45 \end{bmatrix}=\begin{bmatrix} 1890\\ 2125 \end{bmatrix}$ Thus the cost of equipment for the women’s team is 1890, and the total cost for the men’s team is 2125.
