Teacher:You're given a sentence and your task is to classify whether the sentence is acceptable or not. Any sentence which is grammatically correct, has a naturalistic text, is written by a native speaker and which minimizes superfluous content is acceptable, otherwise unacceptable. If the sentence is acceptable then write "acceptable", otherwise "unacceptable".
Teacher: Now, understand the problem? Solve this instance: Carmen purchased a dress at Bloomingdale's for $50.
Student:
acceptable
