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:

n = 3 --- i.e. to 3 decimal places

And the variable name is: sales

So, when implemented, the instruction is:

cout <<fixed<< setprecision(3) <<sales;
