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 32.0 mi/gal? Assume that 1 euro = 1.26dollars.

Isn't this mostly a matter of converting units?
I would do this.
Go to google and type in "32 miles to km" without the quotation marks and hit enter. Something like 51 something comes up for km.
113 km/day x 7 days = 791 km/week.
791 km x (1 gallon/51 km) = ?? gallons.
Then type into google 1 U.S. gallon to L and the conversion is about 3.785L or so.
??gallons x (xxL/gallon) = yy L.
L x 1.10 Euro/L = cost in Euros
Then cost in Euros x (1.26 dollars/Euro) = ?? cost in dollars. 
30.00
