Question

A book sold 35,300 copies and its first month of release suppose this represents 9.9% 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

Let be "x" the number of copies that have been sold to date.

According to the information given in the exercise, 35,300 copies represent 9.9% of the number of copies sold to date.

Then, you can set up the following proportion:

`(35,300)/(9.9)=(x)/(100)`

Because "x" represents 100% of the copies sold to date.

Therefore, solving for "x", you get:

`\begin{gathered} ((35,300)/(9.9))(100)=x \\ \\ x\approx356,566 \end{gathered}`

Hence, the answer is:

`356,566\text{ }copies`
