Solve for k, the constant of variation, in a direction variation problem where y = 240 and x = 30.

Minchanka [31]

$\bf \qquad \qquad \textit{direct proportional variation}
\\\\
\textit{\underline{y} varies directly with \underline{x}}\qquad \qquad y=kx\impliedby 
\begin{array}{llll}
k=constant\ of\\
\qquad variation
\end{array}\\\\
-------------------------------\\\\
\textit{we also know that }
\begin{cases}
y=240\\
x=30
\end{cases}\implies 240=k30
\\\\\\
\cfrac{240}{30}=k\implies 8=k$
