I want to get into the university of pennsylvania what do they look for?

The Wharton School at the University of Pennsylvania is the best business program in the country. Like any elite school, they want well-roundedness, but at an extreme level of excellence. You will definitely need as much math as you can get, but don't worry about business courses in high school. That is not what they want; they would rather that you had the most challenging schedule you could have in high school. The business courses you will get once you are in the university.

It sounds like you're on the right track but it is impossible to tell without standardized test scores and grades. The Wharton School, which I'm assuming you're interested in due to your business interests, is incredibly competitive- more or less the difficulty of Princeton or Harvard. Don't worry about taking all the business courses- instead, take the most rigorous all round course load..especially in math if you want to apply for business. UPenn itself is not an easy school to get into and you'll need to not only look good for a UPenn applicant but also good among good applicants if you want to go to Wharton. Even matching the average incoming freshman's scores does not nearly guarantee admission. Aim for at least 1450+ on the SAT, get around 750+ on SAT 2s, and maintain grades as high as possible. Outstanding essays and recommendations will help tremendously.
