I have a business degree (BBA) with a triple concentration in finance, economics and business law. If you are going the marketing route, I would think that you would be taking fewer courses involving mathematics than a finance or accounting major would. Of course, it depends on your university, however at my university all BBA students needed to take two statistics courses, a calculus course, three accounting courses, two finance courses, and two economics courses regardless of their area of concentration, all of which had some mathematical component to them.
I wouldn't be too concerned over having to take course after course involving complex math problems as a marketing major. Even those core courses you may need to take to complete your degree would most likely be no where near the difficulty level of engineering level mathematics.
Again, it depends on your university, but I found that other than the core courses, those who preferred to stay away from math were able to do so for the most part.
