Question

add or remove commas, if necessary, until the sentence has correct punctuation.
at the mall food court, enid sinclair couldnt decide which soda she wanted.

Explanation:

The sentence "At the mall food court, Enid Sinclair couldn't decide which soda she wanted." has correct punctuation. The comma after the introductory prepositional phrase "At the mall food court" is appropriately used to separate the introductory element from the main clause. There is no need to add or remove any commas.

Answer:

The sentence "At the mall food court, Enid Sinclair couldn't decide which soda she wanted." already has correct punctuation, so no changes to commas are needed.
