A book sold 36200 copies in it’s first month of release. Suppose this represents 6.6% of the number sold to date. How many copies have been sold to date?

Round your answer to the nearest whole number

Let x be the number of copies sold to date.

We can set up the following equation:
36200 = 0.066x
Divide both sides by 0.066:
x = 36200/0.066
x ≈ 548484.85
Rounded to the nearest whole number, the number of copies sold to date is 548,485. Answer: \boxed{548,485}.
