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 3.6 L, how much coolant should be drained and replaced with water to reduce the antifreeze concentration to the recommended level?

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 3.6 L, how much coolant should be drained and replaced with water to reduce the antifreeze concentration to the recommended level? : Let x = amt to be drained and amt of water to be added to accomplish this : .75(3.6-x) = .50(3.6) 2.7 - .75x = 1.8 -.75x = 1.8-2.7 -.75x = -.9 x = x = + 1.2 liters to be drained and replaced with 1.2 liters of water
