Roughly how many drops are in a 10 ML bottle of Nude with the Euro dropper?

I plan to wear Nude as my daily standalone around my college campus next semester. However, I would like to plan out my purchases, if possible. At about 3-4 drops daily, I wasn't sure if a 10 ML bottle will last me at least a month or if the 30 ML be a better bargain since I'm using it everyday?

Aboit 320 drops in 10mL, though if yoi're using it every day, a 30mL bottle is a smart investment regardless.
