Answer:
Around 372,527 (rounding down)
Step-by-step explanation:
To solve this, divide the amount of the books sold in the month it was released (33,900) by the percentage of total copies this number represents (9.1% or .091):
33,900/.091 = 372,527.473 or 372,527 (if you round down) or 372,528 (if you round up)
I hope this helps!
