Help please! The radiator in a car is filled with a solution of 75% antifreeze and 25% water. The manufacturer of the antifreeze suggests that for summer driving, optimal cooling of the engine is obtained with only 50% antifreeze. If the capacity of the radiator is 3.9 L, how much coolant should be drained and replaced with water to reduce the antifreeze concentration to the recommended level?
