DuPont claims that its synthetic composites will replace metals in the construction of future automobiles.? "The fuel mileage will? double," says DuPont. Suppose the light and stronger? "composite automobile" will get 50 miles per gallon of? gasoline, and the gasoline costs ?$3.40 per gallon. The anticipated life of the automobile is six ?years, i equals 10 % per? year, and annual travel is 15,000 miles. The conventional car averages 25 miles per gallon. Assume fuel expense is the only expense to be considered. a. How much more expensive can the sticker price of the composite automobile be and still have it as an economical investment for a prospective auto? buyer? b. What is the tradeoff being made in Part? (a)?A. Increased anticipated life of the automobile is being traded off against extra initial investment for the composite car B. Increased mileage per year is being traded off against reduced fuel expense for the composite car C. Reduced fuel expense per year is being traded off against extra initial investment for the composite car D. Increased mileage per year is being traded off against extra initial investment for the composite car
