That's a lot of conversions...
107*7 = 749km in one week
749/1.6 = 468.125 miles
468.125/39 = 12.0032051282 gallons of fuel needed
1 gallon = 4.54609 litres
1.1(Cost per litre)*4.54609(Number of litres per gallon)*12.0032051282(Number of gallons needed) = 60.0244158814 euros cost per week
 60.0244158814 * 1.26 = 75.6307640105 dollar cost per week

Answer:

$ 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
