Final answer:
John should be charged with misdemeanor shoplifting.
Step-by-step explanation:
John should be charged with misdemeanor shoplifting. In this scenario, John entered a store with the intent to shoplift clothing. Shoplifting refers to the act of taking merchandise from a store without paying for it. In general, shoplifting can be categorized as either grand theft or petty theft, depending on the value of the stolen items. Grand theft typically involves items of higher value, while petty theft involves items of lower value. In this case, the value of the clothing is $300. Since the question does not specify the jurisdiction, we can provide a general answer. In many jurisdictions, the threshold for grand theft is usually higher, and stealing clothing worth $300 would likely be considered misdemeanor shoplifting. Misdemeanor shoplifting is a less severe offense compared to felony shoplifting or grand theft.
