Question 6: Assume that you are investigating buying one of three different robots. Use a MARR of 14%. Calculate the ROR to make the economic decision between the robots. \begin{tabular}{|l|c|c|c|} \hline & Robot A & Robot B & Robot C \\ \hline First cost, \$ & ($185,000) & ($160,000) & ($145,000) \\ \hline Annual cost, \$/year & ($10,000) & ($17,000) & ($20,000) \\ \hline Salvage Value, \$ & $15,000 & $10,000 & $9,000 \\ \hline \begin{tabular}{l} Annual Savings, \\ $/year \end{tabular} & $105,000 & $99,000 & $95,000 \\ \hline Life, years & 8 & 8 & 8 \\ \hline \end{tabular} select based upon the IRR? b) What is the incremental IRR between Robot B and C? c) What is the incremental IRR between Robot A and B? d) If you had enough money to buy all 3 of the robots (the robots are independent), which would you select based on a MARR of e) What is the IRR of Robot A? f) What is the IRR of Robot B? g) What is the IRR of Robot C?
