I just drew a blank can someone please help

Answer:
≈ 542,029 copies
Step-by-step explanation:
37,400 copies represents a 6.9% of the total copies sold to date.
Therefore; Copies sold to date will be 100%
Thus;
Total number of copies sold = (37,400/6.9)× 100
= 542,028.99 copies
≈ 542029 copies
2580.6 copies have been sold till date
We need to find the 6.9% of total copies so
6.9% of 37400 would be
=(6.9/100) * 37400
=2580.6
So
2580.6 copies have been sold till date
