In the USA, Sam pays 20.88 US Dollars for 6 US gallons of petrol. In Russia, Leon pays 800 Roubles for 25.58 litres of petrol.

Use the information in the table to compare the prices of petrol in the two countries.

1 US gallon = 3.79 litres
1 Euro = 40.63 Roubles
1 US Dollar = 0.77 Euros

Answer 1

Explanation:

To compare the prices of petrol in the USA and Russia, we can convert the units and calculate the price per litre in both countries. Here's how we can do that:

1. Convert the quantity of petrol in the USA from gallons to litres:

- 6 US gallons = 6 * 3.79 litres = 22.74 litres

2. Calculate the price per litre in the USA:

- Price per litre in the USA = 20.88 USD / 22.74 litres = 0.9172 USD/litre

3. Convert the quantity of petrol in Russia from litres to litres:

- 25.58 litres = 25.58 litres

4. Calculate the price per litre in Russia:

- Price per litre in Russia = 800 Roubles / 25.58 litres = 31.26 Roubles/litre

5. Convert the price per litre in Russia from Roubles to Euros:

- 31.26 Roubles * (1 Euro / 40.63 Roubles) = 0.7683 Euros/litre

6. Convert the price per litre in the USA from USD to Euros:

- 0.9172 USD * (0.77 Euros / 1 USD) = 0.7062 Euros/litre

Now, we can compare the prices of petrol in the two countries:

- In the USA, the price of petrol is approximately 0.7062 Euros per litre.

- In Russia, the price of petrol is approximately 0.7683 Euros per litre.

Therefore, based on the given information and calculations, the price of petrol in the USA is slightly lower than in Russia.
