Write a Python program that allows a boat rental company to calculate the total cost of hiring a motorboat.

The program should:

• allow the user to enter the hire duration in hours (no validation is required)
• allow the user to enter the number of life jackets requested (no validation is required)
• calculate the total hire cost by:
  • charging £5.00 for every life jacket requested
  • charging a further £12.50 for every hour of hire
• output the final calculated hire cost with an appropriate message.

You should use meaningful variable name(s), correct data types, correct syntax, and indentation in your answer.
