Shaftel Ready Mix is a processor and supplier of concrete, aggregate, and rock products. The company operates in the intermountain western United States. Currently, Shaftel has $14$ cement$-$processing plants and a labor force of more than $375$ employees. With the exception of cement powder, all materials $($e$.$g$.,$ aggregates and sand$)$ are produced internally by the company. The demand for concrete and aggregates has been growing steadily nationally. In the West, the growth rate has been above the national average. Because of this growth, Shaftel has more than tripled its gross revenues over the past $10$ years.

Of the intermountain states, Arizona has been experiencing the most growth. Processing plants have been added over the past several years, and the company is considering the addition of yet another plant to be located in Scottsdale. A major advantage of another plant in Arizona is the ability to operate year round, a feature not found in states such as Utah and Wyoming.

In setting up the new plant, land would have to be purchased and a small building constructed. Equipment and furniture would not need to be purchased. These items would be transferred from a plant that opened in Wyoming during the oil boom period and closed a few years after the end of that boom. However, the equipment needs some repair and modifications before it can be used. The equipment has a book value of $$200,000,$ and the furniture has a book value of $$30,000.$ Neither has any outside market value. Other costs, such as the installation of a silo, well, electrical hookups, and so on$,$ will be incurred. No salvage value is expected. The summary of the initial investment costs by category is as follows:

Land $$20,000$
