Question

A book sold 31,700 copies in its first month of release. Suppose this represents 8.8% of the number of copies sold to date. How many copies have been sold to date?
Round your answer to the nearest whole number.

Answer 1

For this case we propose a rule of three:

31700 ------------> 8.8%

x ----------------------> 100%

Where "x" represents the number of copies sold to date.

$x = \frac {100 * 31700} {8.8}\\x = \frac {3170000} {8.8}\\x = 360,227.273$

Thus, to date 360,227 copies of the book have been sold.

ANswer:

To date, 360,227 copies of the book have been sold.
