While in europe, if you drive 113 km 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 39.0 mi/gal? assume that 1euro=1.26dollars?

First let's find total km so 113km per day for 7 days is 791 km. Then we change 791km to miles = 491.211 miles. Since the car is 39 miles per gallon we divide 491.211/39 = 12.60 gallons. We change gallons to liters so we have 12.60gal x 3.785L = 47.67 L at 1.10 euros per liter is 47.67 x 1.10 = 52.44 euros. Finally, change euros to dollars so we get 52.44 x 1.26 = 66.07 dollars.
