The company that you manage has invested $5 million in developing a new product, but the development is not quite finished. At a recent meeting, your salespeople report that the introduction of competing products has reduced the expected sales of your new product to $1.5 million. If it would cost $2 million to finish development and make the product, you (should/should not) go ahead and do so. The most you should pay to complete development is

$ (?) million.
