The equation for Mishra spends on buying x videos is,


y=8x+200

The equation for the cost of selling x videos is,


s=12x

The equation for earnig in the store by selling x videos is,


\begin{gathered} P=12x-(8x+200) \\ =4x-200 \end{gathered}

Substitute 70 for x in the equation to determine the earning from selling 70 videos.


\begin{gathered} P=4\cdot70-200 \\ =280-200 \\ =80 \end{gathered}

So answer is $80.
