Answer:
a. The XC-900 machine provides the following real options to Billingham:
A. The expansion will require additional sales and administrative personnel.
C. If it would be better if production remains the same, Billingham is under no obligation to utilize all of the XC-900 production capacity.
D. The XC-900 allows Billingham the option to expand production starting in year 3.
b. If Billingham knows that it can sell the XC-750 to another firm for $2.19 million in two years, it provides the real option of abandonment or divestment. This means that Billingham has the option to sell the XC-750 and recoup some of the investment if the machine is no longer needed or if a better opportunity arises.
