Explanation:
we know that
36,200 copies represent 8.7% of the number of copies sold to date
so
the number of copies that have been sold to date represent the 100%
using proportion
Find out how many copies have been sold to date
Let
x ---> the number of copies that have been sold to date
![(36,200)/(8.7\%)=(x)/(100\%)\\\\x=36,200(100)/8.7\\\\x=416,091.95\ copies](https://img.qammunity.org/2020/formulas/mathematics/middle-school/cbc6d0ofzxtyadnq1z250x2krudh165cf7.png)
