$\bf \qquad \qquad \textit{direct proportional variation} \\\\ \textit{\underline{y} varies directly with \underline{x}}\qquad \qquad y=kx\impliedby \begin{array}{llll} k=constant\ of\\ \qquad variation \end{array}\\\\ -------------------------------$

$\bf \begin{array}{ccll} \stackrel{x}{packs}&\stackrel{y}{\stackrel{food}{oz}}\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 4&96\\ 5&120\\ 6&144 \end{array}\impliedby \textit{we know that } \begin{cases} x=4\\ y=96 \end{cases} \\\\\\ 96=k4\implies \cfrac{96}{4}=k\implies 24=k$
