    $\begingroup$ Hi! What exactly are you struggling with? $\endgroup$ – Art Oct 9 at 9:04
  • $\begingroup$ Thanks for your attention. Exactly I can not find the optimum values of decision variables. $\endgroup$ – eco20 Oct 9 at 21:21

    $\begingroup$ It'd be great if you could show us the work you've done so far (like the Lagrangian, Euler equation, etc.) and explain where you're stuck. $\endgroup$ – Art Oct 9 at 23:41
  • $\begingroup$ I have added my answer. At first could you tell that Euler equation is correct? Then do you know how i can find the optimum value of L? $\endgroup$ – eco20 Oct 10 at 8:03
