Refer to the following:
The results of a nutritional analysis of one serving of three foods $A, B,$ and $C$ were
Carbohydrates (g) Protein (g) $\quad$ Fat (g)
$$X=\left[\begin{array}{lll}5 & 0 & 2 \\5 & 6 & 5 \\8 & 4 & 4\end{array}\right] \begin{array}{l}A \\B \\C\end{array}$$
It is possible to find the nutritional content of a meal consisting of a combination of the foods $A, B,$ and $C$ by multiplying the matrix $X$ by a second matrix $N=\left[\begin{array}{l}r \\ s \\ t\end{array}\right],$ that is, $X N,$ where $r$ is the number of servings of $f$ ood $A, s$ is the number of servings of food $B$ and $t$ is the number of servings of food $C$.
Find the matrix $N$ that represents a meal consisting of one serving of food $A$ and two servings of food $C$. Find the nutritional content of that meal.
