ABC Mining Company is evaluating ore extraction technology for its new facility. The costs associated with each alternative are shown below. Wet Dry Initial cost, $ 2,000,000 4,500,000 O&M cost, 600,000 120,000 $/year Salvage value, $ 0 150,000 The MARR is 9% per year over a 6-year study period. Assume that one will be chosen. Draw the appropriate cash flow and incremental cash flow diagrams and determine the best alternative based on incremental ROR analysis. (No need to find the exact ROR. Just plug in MARR and provide your conclusion.)
