input: Write a python function to calculate the total price of items for a given customer.
  assert Customer("John").calculate_total([10, 20, 30]) == 60
  assert Customer("Jane").calculate_total([100, 200, 300]) == 600
  assert Customer("Doe").calculate_total([1, 2, 3, 4, 5]) == 15
output: class Customer:
      def __init__(self, name):
          self.name = name
  
      def calculate_total(self, prices):
          return sum(prices)
