   Ovidiu-
   
   I hadn't seen a solution to your problem so I'll throw in mine.
   
   Soln1[t_,c_]:=
   FixedPoint[
     {fm[t,c] t E^(1+#[[2]] c)+3 E^6.5,
      Log[#[[1]]]/l[t,c]}&,{r0,k0}]
   
   This solution repeatedly applies a function to your initial guess for r 
and k (r0,k0).  Nest could be substituted for FixedPoint.  I tested it on 
some arbitrary functions, but I don't know if they are realistic.  The 
above function could be polished to allow r0 and k0 to be input 
interactively.
   
   Hope this helps,
   Daryl
