I am selling a product for $ 3.38 , which cost me $ 3.12. What formula will tell me at what percentage I am selling this for.

Are you really selling a product at a 26 cent markup?



You aren't going to make any money with that margin.

**edited it - just noticed it looked like homework since it was filed under High School.

Come on... really?

In my business that would be an excellent margin!
