Antifreeze is a compound added to water to reduce the freezing point of a mixture. In extreme cold (less than − 35 ° F ), one car manufacturer recommends that a mixture of 65 % antifreeze be used. How much 50 % antifreeze solution should be drained from a 4-gal tank and replaced with pure antifreeze to produce a 65 % antifreeze mixture?
