I recommend the following supplementary courses for you (in order of importance):
Accounting
Finance
Statistics
Microeconomics
I would completely skip business calculus altogether.
DO NOT spend a lot of money on these courses (less than $600 per course recommended). Schools are not impressed by you completing coursework at a highly ranked school. They are impressed with you going out of the way to take supplementary coursework, doing well in the course, and actually learning the material.
You can take the course at a community college--or online like BYU's online course offerings.
Good luck!
