While in Europe, if you drive 105km 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 22.0mi/gal? Assume that 1euro = 1.26 dollars.
22 miles/gallon = 9.35 km/L.
9.35 km/L x ?L = 105 km/day x 7 days
Solve for L, then convert to euros then to $.
