Hints

Create BigDecimal from a String, not a double, to keep it exact.

Solution explanation

new BigDecimal(0.1) is 0.1000000000000000055…; new BigDecimal("0.1") is exactly 0.1.

Show solution

import java.math.BigDecimal;
import java.math.RoundingMode;
import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        int n = sc.nextInt();
        BigDecimal subtotal = BigDecimal.ZERO;
        for (int i = 0; i < n; i++) {
            subtotal = subtotal.add(new BigDecimal(sc.next()));
        }
        BigDecimal tax = subtotal.multiply(new BigDecimal("0.075")).setScale(2, RoundingMode.HALF_UP);
        System.out.println(subtotal.setScale(2, RoundingMode.HALF_UP));
        System.out.println(tax);
        System.out.println(subtotal.add(tax).setScale(2, RoundingMode.HALF_UP));
    }
}
