Bilet altmış lira.

Because Turkish often leaves out a separate present-tense to be in 3rd-person noun/adjective sentences.

So:

• Bilet altmış lira = The ticket is sixty lira

This is completely normal Turkish.
In other words, Turkish does not need an explicit word like is here.

You do see a visible to be-type ending in other persons, for example:

• Ben öğrenciyim = I am a student
• Sen yorgunsun = You are tired

But in 3rd person, it is often just omitted.

Because bilet is just the noun being talked about, so it stays in its basic form.

In this sentence, bilet functions like the subject/topic, and Turkish normally uses the bare form for that.

So:

• bilet = base form
• no extra ending is needed

Turkish adds endings only when grammar calls for them, such as possession, object marking, location, and so on.

It can be either, depending on context.

Turkish does not have articles like the and a/an in the same way English does. So bilet by itself can mean:

• the ticket
• a ticket
• sometimes even tickets in a general sense, depending on context

For example:

• in a conversation about one specific ticket, it may mean the ticket
• on a sign or price board, it may feel more like a ticket costs sixty lira or tickets are sixty lira each

Context tells you which meaning is intended.

Because in Turkish, nouns after numbers normally stay singular.

So Turkish says:

• bir lira
• iki lira
• on lira
• altmış lira

not:

• iki liralar
• altmış liralar

This is a very important difference from English.
After a number, Turkish usually uses the singular noun.

Yes. It is a very natural word order.

Turkish often puts the main predicate at the end, so:

• Bilet = topic / what we are talking about
• altmış lira = what we say about it

So Bilet altmış lira is a normal way to say this.

If the question is already clear, Turkish may also shorten it and just say:

• Altmış lira.

Yes, absolutely.

That version is more explicit:

• biletin fiyatı = the ticket’s price / the price of the ticket

So:

• Bilet altmış lira = shorter, everyday
• Biletin fiyatı altmış lira = more explicit

Both are correct. The shorter version is very common in normal speech, especially when the meaning is obvious.

Yes, you can.

The ending -dır can make the statement sound more:

• formal
• definite
• emphatic
• written or explanatory

So:

• Bilet altmış lira = neutral, everyday
• Bilet altmış liradır = more formal or emphatic

In ordinary conversation, people very often leave -dır out.

Yes.

You will often see or hear:

• Bilet altmış TL

This is very common, especially in:

• signs
• menus
• tickets
• advertisements
• everyday speech

TL is the abbreviation for Türk lirası.
So lira and TL are both normal here.

The letter ı is the Turkish dotless i, and it does not have an exact English equivalent.

A few helpful points:

• it is not the same as i
• it is a back, unrounded vowel
• you should learn it by listening and imitating native pronunciation

Also:

• ş is pronounced like sh

So altmış ends with a sound like -mış, where ş = sh.

A beginner-friendly approximation is possible, but it is better not to rely too much on English spelling, because English does not match the Turkish sounds very well.

Yes, in the right context, it could.

Even though bilet is singular in form, Turkish can use a bare singular noun to talk about the general price of an item.

So on a sign or in a general statement:

• Bilet altmış lira can be understood as
  • A ticket is sixty lira
  • Tickets are sixty lira each

That is why context matters so much in Turkish.
