Final answer:
To calculate the amount of money spent on gas in one week, we need to know the distance traveled in one week and the gas mileage of the car. By converting the distance from kilometers to miles, we can calculate the amount of gas used and the cost of the gas. Therefore, if you drive 121 km per day, the amount of money you would spend on gas in one week is approximately 106.65 dollars.
Step-by-step explanation:
To calculate the amount of money spent on gas in one week, we need to know the distance traveled in one week and the gas mileage of the car. The given information states that you drive 121 km per day. To find the distance traveled in one week, we need to multiply the distance per day (121 km) by 7 days, which equals 847 km per week.Next, we need to convert the distance from kilometers to miles because the gas mileage is given in miles per gallon. Using the conversion factor of 1 kilometer = 0.621371 miles, we can calculate that the distance traveled in one week is approximately 527.0328 miles.
Now, let's calculate the amount of gas used in one week. Given that the car's gas mileage is 26.0 mi/gal, we can divide the distance traveled in one week (527.0328 miles) by the gas mileage (26.0 mi/gal) to find the amount of gas used. This equals approximately 20.2697 gallons of gas.
Therefore, if you drive 121 km per day, the amount of money you would spend on gas in one week, at a rate of 1.10 euros per liter, with a gas mileage of 26.0 mi/gal and an exchange rate of 1 euro = 1.26 dollars, is approximately 106.65 dollars.
