"An airline is considering two types of engine systems for use in its planes. Each has the same life and the same maintenance and repair record. SYSTEM A costs $107,000 and uses 26,000 gallons of fuel per 1,800 hours of operation at the average load encountered in passenger service. SYSTEM B costs $214,000 and uses 18,000 gallons of fuel per 1,800 hours of operation at the same level. Both engine systems have three-year lives. Each system's salvage value is 9.9% of its initial investment. If jet fuel currently costs $2.67 a gallon and fuel consumption is expected to increase at the rate of 7.2% per year because of degrading engine efficiency, which engine system should the firm install? Assume 2,500 hours of operation per year and a MARR of 11.1%. Use the annual equivalent cost criterion. What is the annual equivalent cost of the preferred engine?"
