Saved a checkpoint:
I made this question after Vicky suggested making a question where the student is asked to find the original 100% value given a value of for example 85%, because many students seem to struggle with this type of a question. If it needs any adjustments, please make sure the focus is still on finding the original 100%.

Thank you, I've reworded the question how you suggested. You were right about the fact that buying a fridge impulsively is a bit silly and unrealistic haha so I removed it now.

 Are you absolutely sure you want to pick fridge as an option for the object? The scenario talks about Josh really liking Emily's fridge and thus buying it on a bit of a whim, but I don't think that really happens with fridges! I think you'd only purchase it if your fridge happened to be broken. It is quite funny though so up to you whether you keep or change it.
 I would reword parts of the question slightly, just to make the focus a bit stronger. Part a)  "When Josh told Emily how much he had paid for the {item}, Emily said the price had decreased by 30% since she bought it. How much did Emily pay for the fridge?"
 Good, clear advice!
 I think the question is really good and a valid realworld example scenario!

I have fixed everything. There is a different price range for every item, I made sure these are all realistic compared to the actual market right now.
All the original prices now end with .99. It would not be random enough if I still wanted the discounted price to end with .99 as well and still have integer percentages, so now, the new discounted price ends with .x9. I think this is good and realistic enough.

Saved a checkpoint:
Currently, the maximum price that can be picked is £800, and the maximum percentage change is 30%, giving a maximum original price of £1143. That's an enormous amount of money for a smartphone or a console! Maybe use a different range of prices for each item.
The "original" prices don't seem very realistic  they would typically be £xxx.99, just like the discounted price. Can you round off the original price, and make sure that the percentage discount is still the same?

Thank you Hannah. I removed the first part of my advice.

I corrected some grammar in the statement and question, but otherwise I think it sounds good.
I'm not sure you need the first part of your advice becase I don't think students would find it helpful compared to your actual advice.
I don't think Divide needs a capital d as it is the middle of a sentence.
otherwise I think your question looks good

Test that the marking algorithm works
Check that the marking algorithm works with different sets of variables and student answers using the interface below.
Create unit tests to save expected results and to document how the algorithm should work.
There's an error which means the marking algorithm can't run:

To account for errors made by the student in earlier calculations, replace question variables with answers to earlier parts.
In order to create a variable replacement, you must define at least one variable and one other part.

The variable replacements you've chosen will cause the following variables to be regenerated each time the student submits an answer to this part:
These variables have some random elements, which means they're not guaranteed to have the same value each time the student submits an answer. You should define new variables to store the random elements, so that they remain the same each time this part is marked.
