PLEASE HELP! 35 PTS! Microsoft is finally selling copies of the Windows 10 operating system to vendors. It has been a long development period! They have invested over $315 million in development costs. They figure the average monthly demand for the first two years will be 580,000 units per month. Their unit cost is pretty low, just the cost of pressing a disk and packaging, or sold as a download. Thus the unit cost is $2.70 per copy. A what price should they sell windows 10 copies to vendors in order generate a profit of $1.16 billion in 23 months?
