The concentration, $C$ (in mg/L), of a drug in a patient’s bloodstream is modeled by the function $C(t) = rac{5te^{-0.2t}}{1 + t}$, where $t$ is the time in hours since the drug was administered. Determine the rate of change of the drug’s concentration with respect to time at $t = 2$ hours. Explain whether the concentration is increasing or decreasing at this time.
