Solve the following python programming problem given the following code:
# Add a static method called make_money_sound()
# create the Client class below
class Client(object):
    def __init__(self, name, balance):
        self.name = name
        self.balance = balance + 100
        
        #define account level
        if self.balance < 5000:
            self.level = "Basic"
        elif self.balance < 15000:
            self.level = "Intermediate"
        else:
            self.level = "Advanced"
    
    def deposit(self, amount):
        self.balance += amount
        if self.balance < 5000: 
               self.level = "Basic"
        elif self.balance < 15000:
               self.level = "Intermediate"
        else: 
               self.level = "Advanced"
        return self.balance
   
    def withdraw(self, amount):
        if amount > self.balance:
            raise RuntimeError("Insufficient for withdrawal")
        else:
            self.balance -= amount
        return self.balance
            
    @staticmethod
    def make_money_sound():
        print("Cha-ching!")
        
    

Client.make_money_sound()

C1.make_money_sound()
Given the above code, generate some markdown instructions for it.

#Here is the Python program you requested.

Challenge:
can we write this Class in a more efficient way to not repeat assigining the balance?
Static Methods
Static methods are methods that belong to a class but do not have access to self and hence don't require an instance to function (i.e. it will work on the class level as well as the instance level). 
We denote these with the line @staticmethod before we define our static method.
Let's create a static method called make_money_sound() that will simply print "Cha-ching!" when called.
