Textbook Question
Chapter 7, Problem 4DMC
Research. Estimate how much you (or a friend) spent on gasoline in the past year, as well as the mpg rating of the vehicle driven. Then find the combined city and highway gas mileage of a more efficient vehicle. How much less would you have paid last year for gasoline if the more efficient vehicle were driven? How much would it cost to trade for the more efficient vehicle? Assuming your gas usage and the gas prices stay constant, how long would it take to pay for the more efficient vehicle?
