Question

*HELP PLEASE*

A book sold 32,100 copies and its first month of release. Suppose this represents 8.1% 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

We can write an equation from this question:

`(32100)/(8.1) = (x)/(100)`
Set the denominators equal:

`(396296.296296296)/(100) = (x)/(100) \\ \\ x = 396296`

Answer 2

To find the total number of copies, divide the number sold by the percentage sold:

8.1% = 0.081

32,100 / 0.081 = 396,296

Double check by multiplying the answer by 8.1%:

396,296 x 0.081 = 32099.9 = 32,100

Total sold = 396,296
