Answer 1

The issue is in rounding up.
you just converted double to int. that's not rounding up.
rounding up always gets the next whole number.
3.1 rounded up = 4
3.8 rounded up = 4
delete the conversion
and use Math.ceil(),
(int) is just there to get rid of decimal point.

// converts sum to integer
// int finaleCost = (int) sum;
System.out.println((int)Math.ceil(sum));
