\(\large \begin{align} \color{black}{\normalsize \text{Amelia paid 252 for 28 cases of granola bars for the snack bar. } \hspace{.33em}\\~\\
\normalsize \text{The total cost varies directly with the number of cases purchased ,so } \hspace{.33em}\\~\\
\normalsize \text{let the total cost be x } \hspace{.33em}\\~\\
\normalsize \text{let the number of cases be y } \hspace{.33em}\\~\\
x\alpha y \hspace{.33em}\\~\\
x=ky \hspace{.33em}\\~\\
k=\dfrac{x}{y} \hspace{.33em}\\~\\
k=\dfrac{252}{28} =9 \hspace{.33em}\\~\\
x=9\cdot 10=90 \hspace{.33em}\\~\\
