A street vendor at a parade sells fresh lemonade, soda, bottled water, and iced$-$tea, and the sold of each item is given in matrix $N.$ Compute $NP$ and interpret the result.

$N=\left[\begin{array}{cccc}\text{L}\text{e}\text{m}\text{o}\text{n}\text{a}\text{d}\text{e}& \text{S}\text{o}\text{d}\text{a}& \text{W}\text{a}\text{t}\text{e}\text{r}& \text{T}\text{e}\text{a}\\ 280& 250& 150& 260\end{array}\right],P=\left[\begin{array}{c}\text{\$}1\mathrm{.}80\\ \text{\$}3\mathrm{.}00\\ \text{\$}3\mathrm{.}00\\ \text{\$}1\mathrm{.}50\end{array}\right]$ Temonade
