Homework Help: Differential equation

  1. Jun 17, 2008 #1
    1. The problem statement, all variables and given/known data

    The concentration of a particular drug in a patient’s bloodstream declines at a rate proportional
    to the concentration, with constant of proportionality k = 0.2 if time is measured in hours. If
    the concentration of the drug in the patient’s bloodstream is 10mm/ml (millimoles per milliliter)
    shortly after the injections, what will the concentration be 12 hours later?

    2. Relevant equations

    3. The attempt at a solution
    Just want to know if I set this one up correctly.
    If I didn't, don't be afraid to rip it apart :D.

    That looks like what the problem is asking for all right.

    Okay, thanks! Then I must've messed up when I integrated it.
