When people take a certain drug, the drug is metabolised and eliminated at a certain rate. Suppose the initial amount of a drug in the body is 200 mg and is eliminated at a rate of 30% per hour. Which equation describes the decrease in the amount of drug over time? Where: X(t) is the amount of drug at time (t) t is the time in hours Select one: a. X(t) = 200 (1.3)t b. X(t) = 200 (0.7)t c. X(t) = 200 (0.3)t d. X(t) = 200 (t)0.7
