Mr. Wise buys fuel at three various gas stations – MOL, Shell and EuroOil. He always buys \(25\) liters of diesel, cafe latte and \(2\) nougat croissants.
\[~\]
Prices in CZK:
\[ \begin{array}{|c|c|c|c|} \hline &\text{Diesel (}1~\text{liter)} &1~\text{Cafe Latte}&1~\text{Croissant}\\\hline
\text{MOL}& 31.20& 57&16.90\\\hline
\text{Shell}& 27.20 &52 &20 \\\hline
\text{EuroOil}& 29.60 &49 &18.20 \\\hline
\end{array}\]
Consider the next product of the two matrices:
\[
\left (\array{
31.20& 57 & 16.90 \cr
27.20& 52 & 20 \cr
29.60& 49 & 18.20 \cr }
\right )
\cdot
\left (\array{
25 \cr
1 \cr
2 \cr
}
\right )
\]
Choose the statement which is NOT true:
The most optimal prices are at the MOL gas station.
The most optimal prices are at the Shell gas station.
The least optimal prices are at the MOL gas station.
