Official Curriculum Content Description:
use mathematical modelling to solve applied problems involving linear relations, including financial contexts; formulate problems with linear functions, choosing a representation; interpret and communicate solutions in terms of the situation, reviewing the appropriateness of the model
This descriptor is not included on paper worksheets because it requires physical materials, digital tools, or classroom investigations:
Requires an open-ended mathematical modelling cycle formulating problems with linear functions and evaluating the model. A swap to another question was considered: no linear-relations generator on the paper models a financial or applied scenario (the paper's questions expand, factorise and solve graphically), so nothing can be re-mapped.
