The statement tells us several important things

1. ,2n the first month 41000 copies were sold.

2. the 41,200 copies correspond to 8.8% until today

We are asked to find how many copies have been found so far, i.e. 100% of the books sold.

To do this, we first find the value of 1% i.e. we divide the copies sold in the first month by 8.8.

After this, we multiply by 100 to find 100 % so we can pose the following equation where S100 is the total number of copies sold.


\begin{gathered} S_(100)=41200\cdot(100)/(8.8) \\ S_(100)=468,181.8182 \\ S_(100)\cong468,182 \end{gathered}

In conclusion, as of today, approximately 468,181 have been sold.
