$1).$ A $($initial capital$)$ revamping project is currently underway for the receiving dock of a hardware wholesaler. The completed project is expected to provide future benefits for which the wholesaler would have been willing to pay up to $x if necessary. However, new information has been received that the entire facility will be shut down when its lease expires, leading to a new estimate that the future benefits of the revamp are worth only $y$.$ If the revamping project is curtailed quickly, the wholesaler can save the last $z of its cost. Should this be done?
