Question

A book sold 33,400 coples in its first month of release. Suppose this represents 7.6% of the number of coples sold to date. How many coples have been sold todate?Round your answer to the nearest whole number.

Answer 1

The number sold in the first month is given as 33,400.

This number is 7.6 percent of the total copies sold till date. This means x copies have been sold till date, and x copies represents 100 percent.

Therefore, you would have the following proportion;

`\begin{gathered} (33400)/(x)=(7.6)/(100) \\ \text{Cross multiply and you'll have;} \\ (33400*100)/(7.6)=x \\ 439473.684210\ldots=x \\ x\approx439474\text{ (rounded to the nearest whole number)} \end{gathered}`

The number of copies sold till date is 439,474 (rounded to the nearest whole number)
