Respuesta :

Let x be the number of movies you watch.

Option A will cost you:

[tex]20x+160[/tex]

Option B will cost you:

[tex]40x[/tex]

The two options will cost the same when:

[tex]\begin{gathered} 20x+160=40x \\ 160=40x-20x \\ 20x=160 \\ x=\frac{160}{20} \\ x=8 \end{gathered}[/tex]

Therefore, after 8 movies the two options will cost the same.
