Its rate has to be adjusted for an entertainer (7)

I believe the answer is:

artiste

I'm a little stuck... Click here to teach me more about this clue!

'for an entertainer' is the definition.
(artiste is a kind of entertainer)

'its rate has to be adjusted' is the wordplay.
'its rate' anagrams to 'ARTISTE'.
But, I'm not sure how the anagram is indicated.

Can you help me to learn more?

(Other definitions for artiste that I've seen before include "'Public performer, dancer or singer (7)'" , "A sitter for creative person" , "Attires like entertainer" , "Attires (anag.)" , "Theatre performer" .)

I've seen this clue in The Globe and Mail.
