One of my pupils requested some questions similar to an Edexcel Mock which involved creating two equations, solving one and substituting into another. Harder questions usually involve setting up non-replacement but this was a nice question on replacement trees. I built a series of questions on the same one with variations as well as model to help understanding.

I have included a model, blank tree diagrams, questions and solutions
