(1) After a large number of drinks, a person has a blood alcohol level of 200 mg/dL (milligrams per deciliter). The amount of alcohol in the blood decays exponentially, with one fourth of the alcohol being removed every hour, in the form y = 4(e"), where y is the amount of alcohol in the blood after t hours. Determine how many hours will take for the person's blood alcohol level to decrease to 80 mg/dL?
