    10 pts. Making exponential functions?

    Guaranteed 10 pts to first best answer The rate of change in sales S is inversely proportional to the time (t>1). Find S as a function if sales after 2 and 4 weeks are 200 and 300 respectively. So I got dS/dt=1/t and S=ln|ct| I try to find the constant, but I'm not sure about it. Help? Thanks...
