Advantgard Company plans to make a "green" investment in its forklift truck fleet. A hydrogen fuel-cell powered forklift will do the work of three battery-pack forklifts because of the time required to recharge the batteries. If the MARR is 14% per year, which type of forklift should be recommended? Use the IRR method. The salvage values of both types of trucks are negligible. Battery (three trucks) Hydrogen (one truck) Initial investment 250,000 400,000 Cost of operation 60,000 30,000 Useful life, years 5 8
