I explain how to set up the problem using algebra and a tree diagram to find the number of green pens. We determine that there are three more blue pens than green, and the total exceeds 12. After working through the calculations, I find that the possible values for green pens are 4 or 21, but only 21 meets the criteria. I encourage you to review the steps and ensure you understand the process.
