You purchase 4 videos
The original price of each video is x dollars
You decide to purchase the limited edition versions of the videos for an additional cost
Your total cost is (4x + 20) dollars
So, total additional cost is $20
since, we are purchasing 4 videos
so, additional cost in each videos is


So, limited edition cost additional $5 per videos.........Answer
So we can setup variable equations for this:
so we're given that the length is 22feet longer than the width!
so as an expression length is equal to 22+w
and width as an expression is just w
so the formula for the perimeter for a rectangle is 2l+2w=perimeter
so fill it in now!
1616=2(22+w)+2w
1616=44+2w+2w
1616=44+4w
1572=4w
divide by four..
w=393
and length is simply 22 more than that as stated in the question!
so length is 415
dimensions are: 415x393
