Is your current math at Algebra 2 but you are going to Pre Calc or higher?
DePaul has a Playwriting degree and they note In addition to the major’s requirements, students complete 52 quarterly credit hours (13 courses) in the university’s Liberal Studies Program. Courses are taken in theatre history, writing, quantitative reasoning and technological literacy, philosophical inquiry, religious dimensions, scientific inquiry, understanding the past, multiculturalism in the United States, and electives. These liberal studies courses are scheduled during the first three years of the program.
Others to look at (not sure if can dual):
Ohio U
SUNY Purchase
I think your academic rigor might not be enough based on what you wrote for your reaches and maybe even your safeties - like Wisconsin, which is not a safety - but then your career (acting) background might compensate.
Iowa doesn’t seem to have an undergrad in playwriting.
Good luck.
