B- The ROR for each option, answer the below questions: 1. The ROR for server 1 over 3 years operation equal = 2. The ROR for server2 over 4 years operation equal = 3. The ROR for server 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 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? 7 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 ? B- The ROR for each option, answer the below questions: 1.
