A savings plan simulation deposits an amount equal to twice the day number for 7 days. What total amount is printed at the end?

public class Savings {
    public static void main(String[] args) {
        int total = 0;
        for(int day = 1; day <= 7; day++) {
            total += day * 2;
        }
        System.out.println(total);
    }
}
