Questions & Answers about Этот билет стоит сто долларов.
Why does долларов end in -ов?
This is the genitive plural form of доллар. Because доллар is a masculine noun ending in a hard consonant, it takes the -ов ending in the genitive plural. We need the plural here because we are talking about a hundred of them.
Why do we use the genitive plural after the number сто?
In Russian, numbers 5 and above (like 10, 20, 50, and 100) are always followed by the genitive plural of the noun. For comparison, if it cost 1 dollar, it would be один доллар (nominative), and for 2-4 dollars, it would be два/три/четыре доллара (genitive singular).
I thought стоит meant 'stands'. Why does it mean 'costs' here?
The verbs стоять (to stand) and стоить (to cost) look exactly the same in this 'he/she/it' form (стоит), but they are pronounced with different stress! 'Stands' is stressed on the last syllable, while 'costs' is stressed on the first syllable. Context will also clearly tell you which one makes sense.
Why is it Этот билет instead of just using Это билет?
билет (ticket) is a masculine noun, so the describing word 'this' must be the masculine Этот to match it. You use Это when pointing something out as a full sentence (like 'This is a ticket' - Это билет), but when 'this' attaches directly to a specific noun to say 'This ticket...', it acts like an adjective and has to match the noun's gender.
