In reply to Citi.

Fifth Harmony has abot 70-80 when the five of them were together. After she left they sold like 46,000 units (32,000 in traditional album sales). The girl group's last album (with Camila in it), 7/27, also debuted and peaked at No. 4 in 2016 (74,000 in units and 49,000 in sales).

So judging by this, the group did 15K less without her, so we know at minimum she will sell 15K.

I think she may sell about 50K in her first week lol.
