Alya, Robby, and Risa are the main committee of school anniversary. They hold a small meeting.

Alya: Has anyone got any good ideas about what we can do for our school anniversary?

Robby: What about a fashion show?

Risa: We did that last year.

Alya: That's true. Let's do something different.

Robby: I know. What about a band festival?

Alya: A band festival?

Robby: Yes. There are four bands at our school, such as The Highway, Respirant, Skuldude, and The Benhil. I'm sure they would do a show if we asked them.

Risa: I like your idea.

Alya: Me, too. It would be brilliant. Let's do it.

Robby: Okay, so what tasks do we need to think about?

Alya: Well, someone needs to organize it. Talk to the headmaster, ask the bands, see if we can use the school field, things like that.

Robby: I'll do that. I've got friends in all those bands.

Alya: Okay, so Ratih's in charge of the organization. I'll be responsible for the promotion.

Risa: What do you mean?

Alya : Well, I'll promote the show. For example, I'll make posters so people know about the show, and I'll go into classrooms and tell them about the show. I will also get tickets printed, that sort of thing.

Risa: Okay, but what does that leave for me?

Alya: How about security?

Risa: Security?

Alya: Yeah. You can make sure there's no trouble and that everyone's got a ticket.

Risa: Okay. Can I sell tickets, too?

Robby: Sure. What do you think we should charge?

Risa: For four bands, let's say Rp20.000,00.

Robby: So, if we sell 100 tickets, that is Rp2.000.000,00.

Alya: That would be fantastic. Can we give the money to the orphans?

Risa: Why not? It's a charity.

Robby: Fine by me.

Alya: Okay. Let's do it.

What tasks should they do for the event?
