Given that the price per microprocessor in the above function equals $5.60 and that the software component consists of 1,200 lines-of-code at $120/line-of-code, determine the difference in cost-per-unit (unit is all the hardware and software required to implement the function) to support each of the three forms of fault tolerance. Note that if multiple microprocessors are used, they still may use the same software. Furthermore, assume that the company is planning to sell 100,000 units.
