input: Write a python function to calculate the total cost given two lists, prices and quantities.
  assert calculate_total_cost([12, 10, 5, 8], [1, 2, 3, 4]) == 70
  assert calculate_total_cost([15, 20, 30], [2, 3, 1]) == 125
  assert calculate_total_cost([7, 3, 9], [5, 2, 4]) == 86
output: def calculate_total_cost(prices, quantities):
      return sum(p * q for p, q in zip(prices, quantities))
