Answer:
487=3x-17
487+17=3x-17+17
3x=53
3x/3=53/3
x=168
Step-by-step explanation:
Should be chosen the bigger propability
0,6>0,4
For this case we propose a rule of three:
31700 ------------> 8.8%
x ----------------------> 100%
Where "x" represents the number of copies sold to date.
![x = \frac {100 * 31700} {8.8}\\x = \frac {3170000} {8.8}\\x = 360,227.273](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%20%7B100%20%2A%2031700%7D%20%7B8.8%7D%5C%5Cx%20%3D%20%5Cfrac%20%7B3170000%7D%20%7B8.8%7D%5C%5Cx%20%3D%20360%2C227.273)
Thus, to date 360,227 copies of the book have been sold.
