It's hard to say. I can see what you see: your DAT is a bit low for them but your GPA is higher and your ECs look good to me. I don't think that anyone can tell you anything definitive because as much as numbers matter, admissions isn't a hard and fast numbers game. It's hard to tell how your application will come across without being familiar with how Penn evaluates applications.
I will tell you that I interview high school students seeking admission to my undergraduate university and this year I met a student who impressed me a great deal during the interview, but whose GPA, test scores, and extracurriculars were a bit lacking in what would generally be considered an ideal student to the college. I wrote her an amazing rec as well as pulled some strings and she ended up waitlisted and then denied. I think if it had been only one factor that had been somewhat lacking she might have been accepted.
I don't know whether Penn will be a reach for you or whether the rest of your package will impress them so much that the DAT won't matter as much in their minds. Therefore I encourage you to apply if you really want to go there. If you're not interested...well then you should consider replacing it with a different school that you want to attend. Again, it's up to you.
