and the accompanying computer equipment necessary to place this technology in a wide variety of harsh environments-chemically toxic to humans, in flight, underground in mines, on the ocean floor, in war-torn areas, etc. Information summarized below. Case Study Exercises Use spreadsheet analysis to determine the following: A- If the MARR =12%, which server should be selected based on PW method to make the selection, (Hint: You have to use LCM for PW calculations) answer the below questions: 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? B- The ROR for each option, answer the below questions: 1. The ROR for server1 over 4 years operation equal = 2. The ROR for server 2 over 4 years operation equal = 3. The ROR for server3 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 the below questions As per the Descartes rule of signs for the NCF between servers 183 , 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 1&3 if exist? 4. Based on the incremental analysis which option we should select if incremental analysis is applicable? and the accompanying computer equipment necessary to place this technology in a wide variety of harsh environments-chemically toxic to humans, in flight, underground in mines, on the ocean floor, in war-torn areas, etc. Information summarized below.
