Answer :
To find out how many pounds of CO2 Harry's vehicle will add to the atmosphere in a year, we need to follow these steps:
1. Determine the number of gallons of gasoline used in a year:
- Harry drives 15,000 miles in a year.
- His car travels 25 miles on one gallon of gas.
- Therefore, the number of gallons of gasoline used in a year is calculated by dividing the total miles driven by the car's miles per gallon performance:
[tex]\( \frac{15000 \text{ miles}}{25 \text{ miles per gallon}} = 600 \text{ gallons} \)[/tex]
2. Calculate the total CO2 emissions per year:
- Burning one gallon of gasoline releases 20 pounds of CO2.
- Harry uses 600 gallons of gasoline in a year.
- Therefore, the total CO2 emissions per year is calculated by multiplying the number of gallons of gasoline used by the amount of CO2 released per gallon:
[tex]\( 600 \text{ gallons} \times 20 \text{ pounds per gallon} = 12000 \text{ pounds} \)[/tex]
So, Harry's vehicle will add 12,000 pounds of CO2 to the atmosphere in a year.
