Total number of copies sold to date = 361628.

Step-by-step explanation:

Let the number of copies sold to date = a

It's given that number of copies sold in the first month = 31100

These copies were 8.6% of the number of copies sold to date.

Therefore, 8.6% of a = 31100

a ×

a =

a = 361627.907

a ≈ 361628

Therefore, total number of copies sold to date = 361628.
