Medicine taken by a patient breaks down and eventually leaves the patient’s system. Suppose a dose of 60 milligrams (mg) of medicine is given and it breaks down such that 20% of the medicine becomes ineffective every hour. How much of the 60 mg dose is still active after 3 hours, after 4.25 hours, after hours?
