Exercise 23

The per-unit cost of an item is its average total cost (= total cost/quantity). Suppose that a new cell phone application costs $100,000 to develop and only $.50 per unit to deliver to each cell phone customer. What will be the per-unit cost of the application if it sells 100 units? 1000 units? 1 million units?
