The limited edition cost additional $5 per videos
Solution:
Given that,
you purchase 4 videos
The original price of each video is x dollars
Therefore,
Cost of 4 videos = 4x dollars
You decide to purchase the limited edition version of the videos for an additional cost
your cost is (4x ± 20) dollars
So, total additional cost is $20
We are purchasing 4 videos
Therefore,
[tex]\rightarrow \frac{20}{4} = 5[/tex]
so, additional cost in each videos is $ 5
Thus the limited edition cost additional $5 per videos
Which means, when you purchase limited edition version of the videos, it adds up $ 5 for each video to original cost of each video
