While in europe, if you drive 107km per day, how much money would you spend on gas in one week if gas costs 1.10 euros per liter and your car's gas mileage is 39.0mi/gal ? assume that 1euro=1.26dollars.

$ 62.578  

Explanation:

Conversion factors:

1 gal = 3.785 L

1.609km = 1 mi

$1.26 = 1 euro

1 week = 7 days

Converting the car’s mileage from mi/gal to km/L

39 mi/gal x 1 gal/3.785L x 1.609km/1 mi = 16.578 km/L

Finding the L required in a day

107 km x 1L/16.578 km = 6.45 L  

Finding the euro spent in day

1.10 euro/L x 6.45 L = 7.095 euro/ day

Finding the euro spent in a week and converting it to dollars

7.095 euro/ day x 7 days x $1.26/ 1 euro = $ 62.578
