Minimum wage and Unemployment

I only need help to make the tables and charts more readable; I want the to look similar to the ones in “ECON “3161 Final Paper (1).pdf” I am using that paper as a reference of how I should look like.To be clear (R files (1).zip) is the coding part of my project and (Minimum wage and Unemployment (1).pdf) is the writing part. The last document references how my paper should look in structure and style. So I need my tables and charts to be more readable
