Based on the code snippet above, which describes the state of a and b after transferTo executes?

public class BankAccount {
    private String accountNumber;
    private double balance;

    public BankAccount(String accountNumber, double balance) {
        this.accountNumber = accountNumber;
        this.balance = balance;
    }

    // Moves money from this account into another account
    public BankAccount transferTo(BankAccount other, double amount) {
        this.balance -= amount;
        other.balance += amount;
        return other;
    }

    public double getBalance() {
        return balance;
    }

    public static void main(String[] args) {
        BankAccount a = new BankAccount("A", 50.0);
        BankAccount b = new BankAccount("B", 10.0);
        a.transferTo(b, 15.0);
        System.out.println(a.getBalance() + "," + b.getBalance());
    }
