The concentration, $C$ (in mg/L), of a drug in a patient’s bloodstream is modeled by the function $C(t) = t e^{-0.2t}$, where $t$ is the time in hours since the drug was administered. Determine the rate of change of the drug concentration with respect to time at $t = 5$ hours. Explain what this value indicates about the drug concentration at that specific time.
