A community-supported agriculture (CSA) scheme distributes organic vegetable boxes. The standard charge is £4.20 per kilogram of produce. If the subscriber has a 'Harvest Share' membership, this rate is reduced to £2.50 per kilogram.

Write an algorithm to:

  • take as input the weight of the vegetable box (in kilograms) and whether the subscriber has a 'Harvest Share' membership
  • calculate and output the total charge for the box
  • repeat this process continually until the user enters a weight of 0.

You must use either:

  • Exam Reference Language, or
  • a high-level programming language that you have studied (e.g. Python, C#, Java).
