Answer:
The statement is as follows:
cout <<fixed<< setprecision(3) <<sales;
Explanation:
Here, I assume that the variable has already been declared.
The syntax to use is:
cout<<fixed<<setprecision(n)<<variable-name;
In this case:
[tex]n = 3[/tex] --- i.e. to 3 decimal places
And the variable name is: sales
So, when implemented, the instruction is:
cout <<fixed<< setprecision(3) <<sales;
