Step-by-step explanation:

In a 9x9 feet area, an estimate of fifteen people can fit in, which means that


\begin{gathered} 9*9=81 \\ \\ 15\text{ per }81\text{ square feet} \end{gathered}

Calculate the area for 7 feet by 1 mile


\begin{gathered} \text{Convert 1 mile into feet first} \\ 1\text{ mile }=5280\text{ feet} \\ \\ 7*5280=36960\text{ square feet} \end{gathered}

Divide by 81, and multiply by 15


\begin{gathered} \text{Let }x\text{ be the estimate for the number of people who can fit in} \\ (x)/(36960)=(15)/(81) \\ x=36960\cdot(15)/(81) \\ x=6844.4444 \end{gathered}

Answer:

Rounding our answer to the nearest whole number, we can estimate that 6844 can stand to watch the school parade.
