Should you consider fuel efficiency, measured in miles per gallon, when buying a new car? Suppose that car A costs $16,000 and gets 25 mi/gal, whereas car B costs $31,000 but gets 40 mi/gal. Further, assume that the price of gasoline is $4/gal and that you plan to drive the car for m mi. Taking into account price and fuel efficiency only, complete the following. (a) Write an expression CA for the cost of car A. CA - (b) Write an expression Cg for the cost of car B. CB = (c) How many total miles m would you have to drive so that the cost is the same for both cars? mi
