Learn Polish: Czy ten laptop kosztuje pięćset złotych? - Does this laptop cost five hundred zlotys?

It combines pięć (five) and set (a form of the word for hundred). In Polish, hundreds from 500 to 900 end in -set. So, 500 is pięćset, 600 is sześćset, and so on.

Why is the currency written as złotych instead of złote?

After numbers five and above, including large round numbers like pięćset, Polish requires the noun being counted to be in the Genitive plural case. That is why we use złotych instead of the basic plural złote (which is used for numbers ending in 2, 3, or 4).

Why do we use ten before laptop?

Laptop is a masculine noun. Because it is the subject of the sentence doing the costing, it stays in the basic Nominative case. The word for 'this' that matches a masculine Nominative noun is ten.

Can I ask this question without using the word czy?

Yes! While czy is the standard way to start a yes/no question, you can also just say Ten laptop kosztuje pięćset złotych? and raise the pitch of your voice at the end to show you are asking a question.
