Question 154271This question is from textbook College Algebra
: The radiator in a car is filled with a solution of 60%antifreeze and 40% 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 3.6 L, how much coolant should be drained and replaced with water to reduce the antifreeze concentration to the recommended level?
Please show all steps. This question is from textbook College Algebra

These are the original values:
60% of 3.6=2.16------------------this is the antifreeze
40% of 3.6=1.44------------------this is the water

50% of 3.6=1.8-------------------this is how much antifreeze you want
2.16-1.8=.36---------------------subtract that from what you have

.36L should be drained.
