  assert process_menu({"meals": [{"name": "Pizza", "price": 10}, {"name": "Burger", "price": 5}, {"name": "Salad", "price": 7}]})==22
  assert process_menu({"meals": [{"name": "Pasta", "price": 8}, {"name": "Soup", "price": 6}]})==14
  assert process_menu({"meals": [{"name": "Steak", "price": 20}, {"name": "Fries", "price": 3}, {"name": "Soda", "price": 2}]})==25
output: def process_menu(menu):

      for meal in menu['meals']:
          print(f"{meal['name']}: ${meal['price']}")
          total_price += meal['price']
