input: Write a function to convert a list of Celsius temperatures to Fahrenheit.
  assert convert_to_fahrenheit([30, 15, 17, 18]) == [86.0, 59.0, 62.6, 64.4]
  assert convert_to_fahrenheit([0, 100, -40]) == [32.0, 212.0, -40.0]
  assert convert_to_fahrenheit([25, 30, 35, 40]) == [77.0, 86.0, 95.0, 104.0]
output: def convert_to_fahrenheit(celsius_temps):
      return [(temp * 9/5) + 32 for temp in celsius_temps]
