Question

Southern Georgia school district is considering ordering 48 ​propane-fueled school buses.​ "They're healthier,​ they're cleaner​ burning, and​ they're much quieter than the diesel​ option," said a school administrator.​ Propane-powered buses also reduce greenhouse gasses by 18​% compared to​ gasoline-powered buses and 7​% compared to diesel ones. But they come at a premiumlong dash​$90 comma 000 for a propane​ model, ​$19 comma 000 more than the diesel equivalent. The propane bus operating cost​ (above and beyond fuel​ cost) is 31 ​cents/mile, compared to 40 cents for the diesel. Diesel fuel costs about ​$4​/gallon in​ Georgia, about​ $1 more than propane. Bus mileage is 15 mpg for the propane model vs. 12 mpg for diesel. The life of a school bus in the district averages 12 ​years, and each bus travels an average of 37 comma 000 miles per year because the district is so large and rural. Which bus is the better choice based on a​ life-cycle analysis? The total cost of using one​ propane-fueled bus during its life cycle is ​$ nothing. ​(Round your response to the nearest​ dollar.)
