A CNC lathe, used in a production process, requires a major repair. The machine could either be completely overhauled (repaired) for $x or replaced by a new machine for $1, 100,000.The MARR is 10%. The lathe is required for 5 additional years. The operating and maintenance (O/M) costs and the salvage values for both (existing and new) machines are given below: Determine The equivalent uniform annual cost of keeping (repairing and using) the existing machine if X = 470,000 The range of values of X for which repair would be preferred The yearly saving if the machine is replaced and X = 710,000 The internal rate of return of this project if the machine is replaced and X = 750,000
