Saved a checkpoint:
I've reworded the statement and some of the prompts, and added a separate "simplify your expression step" using patternmatching so that the first one doesn't have to be simplified.
I've also reworded the advice quite heavily.

Thank you, fixed the advice.

Looks good. You still talk about single sweets in part (c) and in the advice, so you'll need to change to packets there too.
Bradley Bush 2 years, 8 months ago
Thank you for the advice. I started with one part, you asked for two and now you've got 3. I did forget to mention that they were super delux sweets, however I have altered them to packets for clarity sake. I have also followed through with the other suggestions you've made.

Chris Graham 2 years, 9 months ago
Why only one part? There doesn't seem to be any good reason why it shouldn't be in two parts.
£2 for a lollipop?! They are unreasonably expensive sweets. May need a rethink to make this more realistic. You state Jerry eats a lot and I would disagree (based on my own sweeteating habits), so perhaps these could be packets of sweets?
You have mixed singular "Jerry", and plural "they".
A good addition would be to add a step to (what will be) part a) which asks for an expression for each of the 3 components. This bit should also be above the cost equation in the advice. "we can see that the unsimplified expression..." can't be seen at all, until those steps have been taken.

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:

When you need to change the way this part works beyond the available options, you can write JavaScript code to be executed at the times described below.
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.
Variable  Answer to use  Must be answered?  

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.
