personal business - should I add this on my app?

<p>Im a Korean international living in the States, currently a highschool junior.
Having read the threads made by other people saying they've been denied by the school after putting their personal business on their resume.</p>

<p>I'll tell you MY poersonal business
Last summer my brother and I did some business selling little chips that inserts into portable gaming device. This was unique in my country, eventhough it was very demended by alot of people. We imported them (about 50 at a time from austrailia) and sold them over the internet (Korean version of ebay). Consequently we'd sold about five hundred of them, making a profit of 12k over three months (sold them for two~three times the money we bought for). It was somewhat of an arbitriage if you could call it one (just kidding haha) and was some serious business considering the fact I was only a sophomore and by bro was a senior at high school. As a consequence it was truely a valuble experience - talking to more then fifty different customers over the phone line and packing over five hundred parcels and especially, making money !
Because my parents didn't make over 100k a year, the entire money was used for my brother's college tuition fees.</p>

<p>Would this business experience work as an advantage for me as a Wharton applicant? and should I cite where all the money was used at?
By the way, I've done landscaping from the beginning of my junior year.(Yes cutting grassed ha ha !) Should I include this in as well? (once a week, seven to eight hours a day).</p>
