This example demonstrates profit and discount calculations using percentages. Key mathematical concepts include percentages, cost price, selling price, and profit/loss. Commands used include Random, Intersect, Polygon, Vector, If, and Segment. Suitable for Grade 1 students.

GeoGebra Commands & Parameters

  1. Random(1, 100) → b
  2. Intersect(xAxis, yAxis) → A
  3. Polygon(A, B, C, D) → q1, a_1, b_1, c, d
  4. Vector(F, E) → u
  5. Polygon(C, D, E, G) → q2, c_1, d_1, e, g
  6. Polygon(C, D, E, G) → q3, c_2, d_2, e_1, g_1
  7. If(f, 1, 0) → f_{1}
  8. If(h, 1, 0) → h_{1}
  9. If(i, 1, 0) → i_{1}
  10. If(j, 1, 0) → j_{1}
  11. Segment(A, E) → l

AI Drawing Prompt Reference

Draw a coordinate system, then draw two line segments from the origin to represent cost price and selling price. Randomly select a point on the selling price segment to indicate the profit point. Next, draw a quadrilateral connecting the origin, the profit point, and the endpoints of the selling price segment. Finally, draw a vector from the origin to the profit point.
