The essay required by the above question is intended to assess your ability to interpret, write and identify rhetorical appeals in a text. For that reason, I can't write the essay for you, but I'll show you how to write it.

First, it is important that you read the entire text “Tipping System Exacerbates Unfair Pay at Restaurants,” understanding the arguments raised by the author and the message that the text is intended to promote.

In this reading, you should analyze how rhetorical appeals were established and developed by the author.

Rhetorical appeals are presented in an essay to convince readers about something. These rhetorical appeals are called ethos, pathos and logos. You can identify them as follows:

Ethos: It tries to convince authors through ethical and moral concepts, showing the good and bad elements in a society and dictating how individuals should act in a correct, fair and positive way.
Pathos: Try to convince readers through sentimentality, showing elements that move the reader and stimulate their emotions.

Logos: Try to convince the reader through logical elements, where the reader must stimulate reasoning, interpretation and thinking.

Once you have identified the rhetorical appeals, you can write the essay as follows:

Introduction: Present the article you reviewed, the author and the main subject of this article.
Body: Write two paragraphs showing how rhetorical appeals are used in this article and what the author's purposes are in using them.
Conclusion: Show how effective the use of these appeals is and how important they are in the text.
