Give the total variable a longer lifetime. As you create it in the loop, it loses all memory from one iteration of the loop to another.
If instead you created it before the loop, then it would persist throughout the entire loop, always keeping the value you put to it so far.

And, again, it would be preferable to update the total first, and to display what's the new total then
Talk to us about this line:
System.out.println("Total balance:"+ (total - y ));
Prefer an int that represents cents instead of representing dollars
Is there another line where you display the total on which you make another operation?
Just have the two lines look the same with similar parentheses
It's weird that you haven't tried
Or just make the program better and don't compute operations in lines that display things
