Write a program (using pseudocode or a programming language of your choice) that allows a drone survey operator to calculate the total invoice amount for a field analysis job.

The program should:

• Allow the user to input the total field area in hectares (no validation is required).
• Allow the user to input the number of specialized drone batteries needed (no validation is required).
• Calculate the total survey cost by:
  • Charging £48.50 per hectare of surveyed land.
  • Charging a flat rate of £18.25 per specialized battery used.
• Output the final total cost with an appropriate, user-friendly message.

You should use meaningful variable names, correct syntax, and appropriate indentation in your answer.
