In French, to make formal questions, we usually invert the verb and its subject (je, tu, nous, vous, ils, elles). See Forming inverted questions in Le Présent (except il, elle, on forms).
However, this method is not as straightforward when the subject is il, elle or on.
Look at these examples:
Va-t-il à Paris?
Is he going to Paris?
Parle-t-elle anglais?
Does she speak English?
Mange-t-on bientôt?
Are we eating soon?
Y a-t-il un problème ? - Oui, il y a un problème.
Is there a problem? - Yes, there is a problem.
Notice that when the verb ends with a vowel (often the case with il/elle/on), then a t must be inserted in-between the verb and il/elle/on with hyphens : -t- .
ATTENTION:
When the verb already ends in a 't' or 'd', you don't need to insert the extra 't' because it's already present (the 'd' is pronounced [t] in these cases):
The same rules apply in questions starting with a question word (que, qui, où, ...):
Que cherche-t-elle ?
What is she looking for?
Où va-t-on ce soir?
Where are we going tonight?
Combien de bouteilles veut-il ?
How many bottles does he want?

Achète-t-il des pâtes? Just to be sure, the translation could be equally, "Does he buy pasta?" and "Is he buying pasta?", is that correct?

Yes, both translations would be correct. The choice depends on context.
