The 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 10% 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) Capital investment Cost of operation Useful life $300,000 $70,000 6 years $40,000 9 years The IRR on (AWHydrogen-AWBattery) is 2620%. (Round to two decimal places.) Select the Hydrogen option. The Advantgard Company plans to make a "green" investment in its forklift truck fleet.
