The corporate average fuel economy(CAFE) standard for mileage is currently 26 miles per gallon of gasoline(the defender) for passenger cars. To conserve fuel and reduce air pollution, suppose the U.S. Congress sets the CAFE standard at 37 miles per gallon(the challenger) in 2010. An auto will emit on average 0.8 pounds of carbon dioxide (CO2) per mile driven at 26 miles pergallon, and it will emit 0.7 pounds of CO2 per mile driven at 37 miles per gallon.

a. How much fuel and carbon dioxide would be saved over the lifetime of a passenger car with the newstandard? Assume a car will be driven 97,000 miles over its lifetime.

b. If CO2 costs $0.03/lb to capture andsequester, what penalty does this place on thedefender? Should this penalty affect the CAFE replacementanalysis?

a. The fuel savings are gallons over the life of the car. (Round to the nearest wholenumber.)

The CO2 emissions"saved" equal to lb of CO2.(Round to the nearest wholenumber.)

b. CO2 penalty for defender is (Round to the nearestdollar.)

This penalty ? the CAFE replacement analysis.
