Answer
The cost of equipment for the women’s team is 1890, and the total
cost for the men’s team is 2125.
Work Step by Step
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.
