C- Use incremental ROR analysis between server 2 and server 3 to decide which is the best option at MARR = 12%. Answer the below questions

1. As per the Descartes rule of signs for the NCF between servers 2&3, what is the maximum number of real_number Delta_i* that exist?
2. As per the Norstroms criterion, is there a one real-positive Delta_i* exist ( enter yes or no) ?
3. What is the value of Delta_i* between server 2 & 3 if exist ?
4. Based on the incremental analysis which option we should select if incremental analysis is applicable ?

For this case, we will analyze the available computers that can provide the server function necessary to make this interlinking available and successful. The first cost and other parameter estimates, including expected contribution to annual net cash flow, are summarized below. Server 1 Server 2 100,000 First cost, $ 100,000 Net cash flow, $/year 35,000 25000 Server 3 150000 50,000 year 1, plus 5000 per year for years 2, 3, and 4 (gradient) 70,000 maximum for years 5 on, even if the server is replaced 5 Life, years 3 4 For this case, we will analyze the available computers that can provide the server function necessary to make this interlinking available and successful.
