Tell me please I need to use the indefinite article in the following sentence.

That phone costs 200 dollars, and that one will cost you (an) extra 50 dollars.

I think because of the adjective extra I need to use the article, but I am not sure. If it is really needed then why?

The indefinite article is used because $50 from somewhere is needed.
If the $50 dollars was specific, you would use "the"

That phone costs $200, and that one will cost you an extra $50.
You should pay for it with the $50 you have in your savings account.

The second sentence also implies you only have $50 in your savings account.

You should pay for the extra $50 from your savings account.

Refers to the specific "extra $50".

    I think the OP's query might be also about an indefinite article + the plural form of a noun - an extra 50 dollars. If it is, then this may be of help – Michael Login Sep 9 '18 at 16:17
  • @MvLog +1 Good point and my use of "$50" needs no explaination. – Peter Sep 9 '18 at 16:25

Something can cost you.

Something can cost (you) extra. extra = more

Something can cost (you) twenty dollars|pounds extra. extra = more

Something can cost (you) an extra extra = additional twenty dollars|pounds.
