Step 1 :\( \frac{18 \text{ lunches}}{6 \text{ min}} = 3 \text{ lunches/min} \)
Step 2 :\( 3 \text{ lunches/min} \times 28 \text{ min} = 84 \text{ lunches} \)
Step 3 :\( \begin{tabular}{|c|c|c|c|} \hline Lunches & 3 & 18 & 84 \\ \hline Time \( (\mathrm{min}) \) & 1 & 6 & 28 \\ \hline \end{tabular} \)
