Question

A book sold 32,700 copies in its first month of release. Suppose this represents 7.4% 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

ANSWER

441891 copies

EXPLANATION

We have that 32,700 copies of a book, sold in the first month, represents 7.4% of the total number of books sold.

Let x represent the total number of books sold.

This means that 7.4% of x is 32,700.

Therefore:

$\begin{gathered} \frac{7.4}{100}\cdot\text{ x = 32,700} \\ \text{Divide through by 7.4 and multiply by 100:} \\ x\text{ = }\frac{32700\cdot\text{ 100}}{7.4} \\ x\text{ }\cong\text{ 441891} \end{gathered}$

441891 copies of the book have been sold to date.
