Implemenation of 'may be used' in Use case diagram

Question

A case diagram has use case "Manage shopping cart". I need to add "View purchase" which used use case "Manage shopping cart" and add "Delete item" which may be used by use case "Manage shopping cart".

My attempt is here: Link

But I am not sure with my implementation of: "which may be used by use case" and orientation direction.

Is that correct?

Wait until the question is closed and you'll see. Btw. Customer, not Costumer. — qwerty_so, Jan 10 '16 at 18:31
I am sorry but when will be question closed? My mistake, rightly is customer. — user4362081, Jan 10 '16 at 19:24
I'm sorry. I meant to say that your question is comprehensible to me. It looks like a school assignment, but without any of the context. — GolezTrol, Jan 10 '16 at 22:29
It is not school assignment or any homework. It is example from school and I do not want to you fill and drawing up but I want only check my result, where is under the link. I am sorry, but I dont know what do you mean "without any of the context" ? I wrote task and my result and I beg control. — user4362081, Jan 10 '16 at 23:51

Obviously, the sentence should be: "which may be used BY use case...". I have edited the question. That can be realized by extend arrow, as you have drawn it.

As for your diagram, it lacks arrows from customer to view content and to delete item. The customer can use these operations, can't he?

I think not because it's accessible via the manage shopping cart. Thank you for editing – user4362081 Jan 11 '16 at 14:33
way of acces doesn't matter. A different functionality is not connected with using it Actor only if he uses a functionality that uses that additional one. You haven't that here. – Gangnus Jan 11 '16 at 14:52
