This is a chemistry question?? Math / chemistry homework help?

When I was recently living in Germany, the cost of gasoline was about 1.60 euro per liter. The most I could pump to fill up the empty tank on my VW Golf was 50.00 euro worth of gas at a time, after which amount the gas pump would shut off. This 50.00 euro worth of gas would last for about 190 km. (A) Given that the currency exchange rate was $1.00 = 1.12 euro, what was the cost of gasoline in dollars per gallon? (B) What was my gas mileage (fuel efficiency) in miles per gallon?
