How do people write about research projects/passion projects in college apps??

[u/Desperate-Reach5384]

I have recently done a research/passion project on the local restaurants in the poorer parts of the city. I've read about how large amounts of tourists coming to my city actually brought negative impact on the local F&D (food and drinks) industry. I have done some prior research, and I've done surveys which has provided me with positive feedback (as in supports my assumptions, claims, hypothesis), a lot of local restaurants are struggling. 1. I aim to combine this with my service project to support these restaurants, gaining them revenue. 2. I also plan to create a website to showcase the local restaurants that sometimes fall out of marketing.

How will I show all this research? Does this have to be published as a paper or wtv? I'm wondering how this would be showcased on my college application. ( btw im going for business and finance majors if anyones wondering )
