Part (b) uses the random variable n={0..4}, but that can give negative sales in a year which doesn't make much sense.  I think that the variable definition has been copied over from a different word type question and should actually be allowed to run {2..5}

J. Richard Snape on Expand brackets and collect like terms 2 years, 10 months ago

Thanks for this fantastic question set in "Transition to University".  I'm trialling using them in my teaching this year.  I have a tiny problem with part h in this question - for some reason when I use it when a student enters a correct answer it marks it wrong, giving feedback that it can be further simplified.  I attach a screenshot - not sure what rule is triggering this as even the 419 constant is prime, so I can't see any further gathering of terms possible.  I'll try to debug myself, but any help would be appreciated :)  It seems to be using "all" for simplification in the marking, but so are other parts in this question that work fine.
