Yeah, we’re busy, but this one has been bugging us. It is an exercise and solution from Cambridge Specialist Mathematics 3&4. It’s basically a PoSWW, or we could simply let it pass as a textbook glitch. But we think there’s more than the obvious to say.
Perhaps people are done, but given the previous discussion, here and (weirdly) here, and a couple requests, it seems worth a shot.
Given VCAA’s pigheaded ramming through of their still-non-existent and now invisible new study design, some teachers have expressed concern about what and how to teach in Specialist Mathematics 1&2 in 2022. One teacher, we’ll call them Mr. Puzzled, emailed us:

The question is worth 5 marks, which equates to 9 minutes of a 3 hour exam (accessible here). The question, and another question (6-ish minutes), which apparently came along for the ride, are posted below. Readers’ homework exercise is to Compare and Contrast.

We’ve now had a chance to look at the exam report. Of course blatantly lying about the screw up in 2(a) is not good, even if it’s par for VCAA’s gutless course. Our comments on this, and everything, are interlaced below, in green.

It consists of the last four parts of Q6, the final question on the exam, concerning a machine that packages noodles. The answers from the examination report appear below the questions.
