Someone has two cars, a large one and a small one. Their fuel tanks have a total capacity of 70 liters. When both tanks are empty, the owner has to pay 45 francs to fill one tank and 68 francs to fill the other. Assume that the person uses regular gasoline for the small car and premium gasoline for the large car, and let the difference in cost between 1 liter of regular gasoline and premium gasoline be 29 centimes (1 centime = 0.01 franc).

What is the capacity of each car's fuel tank?
