Finding the constant of proportionality is equivalent to finding how much the subscription is worth in 1 month. For this, you can use the rule of three
[tex]\begin{gathered} 6\text{ months}\rightarrow\text{ \$}47.94 \\ 1\text{ month}\rightarrow x \\ x=\frac{1\text{ month}\cdot\text{\$}47.94}{6\text{ months}} \\ x=\frac{\text{\$}47.94}{6} \\ x=\text{\$}7.99 \end{gathered}[/tex]Which implies that the subscription of streaming movies every month is worth $ 7.99 and therefore, 7.99 is the constant of proportionality.
