The function D (h)=7e^(-.3h) can be used to find the number of milligrams (D) of a certain drug that is in a patient's bloodstream (h) hours after the drug has been administered. When the number of milligrams reaches 1, the drug will have to be administered again. After how many hours will the drug need to be administered? Please help????

you need to find the time, h, when D=1 so all you need to do is solve the equation: 1 = 7e^(-0.3h)
