Answer 1

Given: A book sold 35,900 copies in its first month of release. Suppose this represents 8.3% of the number of copies sold to date.

Required: To determine how many copies have been sold to date.

Explanation: Let the number of copies sold to date be x. Then according to the question-

`8.3\%ofx=35900`

Simplifying for x as follows-

`\begin{gathered} (8.3)/(100)* x=35900 \\ x=(35900*100)/(8.3) \\ x=432530.12 \\ \end{gathered}`

Final Answer: The number of copies sold = 432,530 (approx).
