Answer: 20,000 pounds of CO₂
Explanation:
30 mpg car.
Number of gallons of gasoline used:
= 60,000 / 30
= 2,000 gallons
CO₂ released = 2,000 * 20
= 40,000 pounds
20 mpg car
Number of gallons used:
= 60,000 / 20
= 3,000 gallons
CO₂ released = 3,000 * 20
= 60,000 pounds
Difference:
= 60,000 - 40,000
= 20,000 pounds of CO₂
