(most of ) Recruter don't really care what is the exact title of your degree. You can put what you want on your resume (computer + business) as long as you can prove it : do you have an official record to attend and pass the class? If yes, there is no issue.

Moreover, you stated that you are a mid-carreer, so if you have 15 years of working experience your degree doesn't really matters, your exprience does.

As the format, go on a job board, look the resume of other people that have the job you want to apply for and take the best of it ( you will see if the business part is important or not).
