Answer 1

To find the price of gasoline in dollars per gallon in Paris, we can follow these steps:

1. Convert the price per liter to price per gallon: \[ \text{Price per gallon} = \text{Price per liter} \times \text{Number of liters in a gallon} \] The average price of gasoline in Paris is 1.91 euros per liter.

   There are 3.785 liters in a gallon. Thus, we calculate: \[ \text{Price per gallon (in euros)} = 1.91 , \text{euros/liter} \times 3.785 , \text{liters/gallon} \] \[ \text{Price per gallon (in euros)} = 1.91 \times 3.785 = 7.22335 , \text{euros} \]

2. Convert the price from euros to dollars: Using the exchange rate of 1.203 euros for 1 dollar, we will find the price in dollars: \[ \text{Price per gallon (in dollars)} = \frac{\text{Price per gallon (in euros)}}{\text{Exchange rate (euros per dollar)}} \] Thus, we have: \[ \text{Price per gallon (in dollars)} = \frac{7.22335 , \text{euros}}{1.203 , \text{euros/dollar}} \] Performing the division: \[ \text{Price per gallon (in dollars)} \approx 6.003229 , \text{dollars} \]

Therefore, the price of gas in dollars per gallon for gasoline in Paris is approximately $6.00.
