Wieviel kostet das?

nehmen = to take.

Ich nehme es = I (will) take it!

OK: We're just counting backwards here, but it can be addictive:




So, let's insert a simple number into the blank to answer the following questions:

--> Frage (question): Wieviel kostet das T-shirt?

--> Antwort (answer): Es kostet zwölf Euro!

--> Frage: Wieviel kostet der Hut?

--> Antwort: Er kostet fünfundzwanzig Euro.

------(Der Hut is masculine, so think about using the masculine pronoun "he" when you answer.)

--> Frage: Wieviel kosten die Stiefel (boots)?

--> Antwort: Sie kosten zweihundert Euro.

----- (Sie = they, since "boots" are plural, which requires a plural verb, therefore the -en ending.)

--> Frage: Wieviel kostet diese paar Stiefel?

--> Antwort: Es kostet zweihundert Euro.

----- (Since you are referring to the boots as a PAIR, you use the singular form of the verb.)
