Solve the problem. A film maker wants to make and sell DVDs of a documentary film. It costs $6500 to make the film and $1500 to set up production. In addition, it costs $4 for each video made. Let P(n) be the price the film maker should set for each video so that it breaks even by making and selling n CDs. Find P(500). What does it mean in this situation?
A. 20; if the film maker charges $20 per video, it will sell 500 videos. B. 17; if the film maker charges $17 per video, it will sell 500 videos. C. 20; if the film maker makes and sells 500 videos, it must sell each video for $20 to break even. D. 17; if the film maker makes and sells 500 videos, it must sell each video for $17 to break even.
