Final answer:
To find the average amount of gasoline and carbon dioxide saved per vehicle, divide the total amount saved by the number of vehicles replaced.
Step-by-step explanation:
To find the average amount of gasoline and carbon dioxide saved per vehicle, we need to divide the total amount saved by the number of vehicles replaced. According to the information given, replacing less efficient vehicles will reduce gasoline consumption by 1.7 million gallons per year and prevent 27 million pounds of carbon dioxide from entering the atmosphere. If we assume that each replaced vehicle saves the same amount, we can divide these totals by the number of replaced vehicles to get the average savings per vehicle.
Therefore, the average amount of gasoline saved per vehicle per year is:
(1.7 million gallons) / (number of replaced vehicles) = average gasoline saved per vehicle
Similarly, the average amount of carbon dioxide saved per vehicle per year is:
(27 million pounds) / (number of replaced vehicles) = average carbon dioxide saved per vehicle
Since the question does not specify the number of replaced vehicles, we cannot determine the exact values for gasoline and carbon dioxide savings per vehicle.
