My car radiator can hold 20 quarts of liquid. Right now it holds a mixture of 25% antifreeze and 75% water. Since winter is coming, I want a higher percentage of antifreeze; my mechanic suggests a 38% mixture. I therefore need to drain off some of the current mixture and replace it with antifreeze. How much of the current mixture do I need to drain off? (Round your answer to 2 decimal places)
