Grad School Potential

<p>Greetings,
I am currently in the first semester of my junior year, declared with a dual degree in Economics (b.a.) and Mathematics (b.s.) with a minor in Chinese. I am interested in applying for Economics grad school, but am unsure of a few things.
Although I am not doing terribly in the upper division math courses (only have 4 classes left to take), my grades are not great. I usually end up with a B or C at the end of the semester. My grades in other classes are fine (A's and B's) but some of the C's are dragging my GPA down nearer the 3.3-3.4 mark.
My question is this: should I continue pursuing the additional math degree or just settle for a math minor. I haven't yet taken real analysis, but I have taken a proofs class (don't know how much weight this will have on my application). Also, if I do drop the math major, would it be smart to drop my current math class (which I will most likely get a C) if it were to lead to a W (withdrawal) on my transcript?
Thank you all very much for your help...</p>
