The Universal Postal Service is considering the possibility of fixing wind deflectors on the tops of 500 of their long-haul tractors. Three types of deflectors, with the following characteristics, are being considered (MARR 10% per year) Blowby $500 21% $3 12 years Windshear Air-vantage Capital investment Drag reduction Maintenance per year Useful life $800 35% $11 12 years $1,300 42% $3 years 117% in drag reduction means 2% in fuel savings per mile, how many miles do the tractors have to be driven per year before the windshear deflector is favored over the other deflectors? Over what range of miles driven per year is air-vantage the best choice? (Note: Fuel cost is expected to be $3.00 per gallon, and average fuel consumption is 5 miles per gallon without the deflectors.) Click the icon to view the interest and annuity table for discrete compounding when the MARR is 10% per year Determine the range over which each deflector is preferred. (Round to the nearest hundreds.)
