This example demonstrates the linear relationship of two friends with different amounts of money over time. Key mathematical concepts include linear equations and linear growth models. It uses GeoGebra commands such as Sequence, RandomElement, Random, and Textfield to construct a dynamic linear growth model. Suitable for middle school and above students to learn the application of linear equations.

GeoGebra Commands & Parameters

  1. Sequence(i, i, 120, (120 * 20), 120) → moneylist
  2. RandomElement(moneylist) → m
  3. RandomElement(daylist) → d_t
  4. RandomElement(daylist) → d_j
  5. Random(50, 150) → k
  6. Random(1, 4) → n
  7. Textfield(a) → InputBox1
  8. Textfield(b) → InputBox2
