I am working on Financial Accounting related question. I see in the Chegg solutions that a journal entry is created for the following question -

Reference - Chapter 2, Problem 12 - Financial Accounting: An Introduction to Concepts, Methods and Uses 14th Edition

Transaction (8): Winkle Grocery store pays $600 for advertisements that will appear next month.

Question - Does this qualify as advertisement expense or prepaid advertisement? In the Chegg solution this is qualified as an expense and I somewhat disagree since the benefits has not been received yet. Can someone please help here.
