Brent received two bills with his monthly gasoline statement. One bill for $92.30 showed he had bought 66L of gasoline and two liters of oil, while the other bill showed he had bought 75L of gasoline and one liter of oil for $100.75. If the price of gasoline and oil remained the same for both purchases, what was the cost per liter of gasoline and per liter of oil?
