Answer: 364,948 copies
Step-by-step explanation:
Hi, to answer this question we have to write an equation:
The number of copies sold to date (x) multiplied by 9.7% in decimal form (divided by 100) is equal to the number of copies sold in the month of release (35,400)
Mathematically speaking:
x (9.7/100) = 35,400
Solving for x:
x (0.097) = 35,400
x = 35,400/ 0.097
x = 364,948
The number of copies sold to date is 364,948.
