Top Gun Records and various movie studios have decided to sign a revenue-sharing contract for DVDs.  Every DVD costs the studio $2 to make.  The DVD will be sold to Top Gun for $3.  Top Gun in turn prices a DVD at $15 and forecasts demand to be normally distributed, with a mean of 5,000 and a standard deviation of 2,000.  Any unsold CDs are discounted to $1, and all sell at this price.  Top Gun will share 35 percent of the revenue with the studio, keeping 65 percent for itself.
