A in Real Real Analysis (the one with Lebesgue Integration, Hilbert Spaces, Lp-spaces, equicontinuity, Fourier Series, etc) so As in all four proof based math classes. Hopefully looks good for Economics grad schools...
And these graduation ceremonies are a pain in the ass, omg. Like 4 hours of waiting for three seconds of accepting your "diploma."
You can get probably get in anywhere, with decent enough letters that I'm sure you have.
I had less math than that and had zero issues getting in nearly everywhere (you'll actually get rejected by some 10-20 schools since they know you can get into the top 10, but apply nevertheless -- it's worth visiting as many departments as possible in flyouts).
Good luck with applications!
