You will find the information you need here. :3 Good luck!

<span>Their progress and wealth is highly dependent on the harvests, and
the price of grain. They probably have to import some industrial
products and if they had a bad year (weather, other catastrophies, poor
technology) they can't get the necessary amount of industrial products
in exchange for their surplus e. g. in grain. </span>
Answer:
1.0236 billion metric tons
Explanation:
Given Parameters
Number of cars = 300000000
Average gas mileage per car = 25 MPG
Average distance covered by a car in one year = 10000 miles
CO2 Emission = 8.53 kg/gallon
Derivations from the given parameters,
If the average gas mileage per car is 25 MPG, then the volume of fuel consumed by a car in a year is:
<em>10000 miles ÷ 25 MPG = 400 gallons
</em>
The CO2 emission for one car in a year is:
<em>400 gallons × 8.53 kg/gallon = 3412 kg or 3.412 metric tons (note: 1000 kg = 1 metric ton)
</em>
The CO2 emission for 300000000 cars in year is:
<em>3.412 metric tons × 300000000 = 1023600000 kg = 1.0236 billion metric tons
</em>
