Question 3 When we take medicine, the drug concentration leaves our blood sttream at an exponential rate. An equation used to model this phenomenom is given by A(t) = Aoe-0.4t, where A(t) is the amount left after t hours, Ao is the initial amount administered, and t is the time in hours. If a patient takes 5 mg of antihistamine, how many milligrams of the drug will be left in his bloodstream after 2 hours? A 2.75 mg 2.25 mg (c) 2.5 mg 3 mg
