Question 855692: An 18-quart car radiator is full of a solution that is 23% antifreeze and 77% water. The car's owner wants to increase the percentage of antifreeze in the radiation to 44% by draining some (but not all) of the original solution from the radiator, and replacing it with pure antifreeze. How much original solution should be drained out and replaced with pure antifreeze to accomplish his goal?
