Six alternatives are nominated for constructing a Mall. The alternatives' investment costs and salvage values are identical. A 10-year study period has been specified, and the MARR is 18% per year. Determine which alternative should be chosen based on the IRR criterion? Suppose we have calculated the IRR on A(C-B) as 12.5%, IRR on A(D-B) as 22%, IRR on 4(E-D) as 20%, and IRR on A(F-E) as 15%.
