Answer:
int newSales;
int totalSales;
Step-by-step explanation:
The code has been written in Java.
To declare a variable in Java, all you need is to give its type followed by the name of the variable and then a semicolon. i.e
[ datatype ] [ variablename ] [ ; ]
In this case the variables are of type integer (int) and there names are newSales and totalSales.
Therefore declaring the variables can be written as follows:
int newSales;
int totalSales;
