A book sold 37,200 in its first month of release. Suppose this represents 8.3% of the number of copies sold to date. How many copies have been sold to date?
Round your answer to the nearest whole number.
Let C be the number of copies sold to date.
We know that 37200 = 8.3/100 * C
Therefore, C = 37200 * 100 / 8.3 = <<37200*100/8.3=448192>>448192. Answer: \boxed{448192}.
