TOT US Case. We Server 1 50.000 Server 2 100,000 Server 3 100000 First cost $ 35,000 28,000 Net cash flow. S/year 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 Case Study Exercises Use spreadsheet analysis to determine the following: A. If the MARR - 129, which server should be selected based on PW method to make the selection (Hint: You have to use 1. The PW for server 1 (4 years) LCM cash flow- 2. The PW for server 2 ( 4 years) LCM cash flow - 3. The PW for server 3 (5 years) LCM cash flow= 4. Based on the PW analysis which option should be selected ? server 1 B- The ROR for each option, answer the below questions: 1. The ROR for servert over 4 years operation equal - 2. The ROR for server2 over 4 years operation equal - 3. The ROR for servers over 5 years operation equal 4. Based on the ROR for each option which option we should select? C-Use incremental ROR analysis between server 1 and server 3 to decide which is the best option at MARR - 12%. Answer 1. As per the Descartes rule of signs for the NCF between servers 183, what is the maximum number of real_number 2. As per the Norstroms criterion, is there a one real-positive Delta_)* existenter yes or no)? 3. What is the value of Delta_i" between server 1 & 3 if exist? 4. Based on the incremental analysis which option we should select. If incremental analysis is applicable
