y= -x/2 + 1 is the answer
The answer above is correct.
Answer: 6
Step-by-step explanation: DE is 4+2 so EF would be the same if it is equal.
For this case we propose a rule of three:
31700 ------------> 8.8%
x ----------------------> 100%
Where "x" represents the number of copies sold to date.

Thus, to date 360,227 copies of the book have been sold.
ANswer:
To date, 360,227 copies of the book have been sold.
26 plus 27 is 53
