1. Assume that machine A has not yet been purchased. What is the annual volume (rounded up to nearest whole number) that would make the company indifferent between the two decision alternatives
(i.e., purchasing and then using machine A to make the switches versus purchasing the switches from
the outside vendor)?
2. Assume that machine A has already been purchased. Is it preferable to use machine A to make the
switches or to purchase the switches from the external supplier?
3. Assume that machine A has already been purchased. At what annual volume level (rounded to the
nearest whole number) should Vista consider replacing machine A with machine B?
4. Use the Goal Seek function in Excel to confirm the volume-indifference level you calculated in
requirement 3.
