The image displays an interior view of a classroom or lecture hall, located in the city of Heilbronn, Germany. The room features white walls, a white ceiling equipped with recessed linear light fixtures, multiple spotlights, and white square acoustic panels. Two white wall-mounted speakers are visible on the left and right sides of the main display. A black analog wall clock, indicating approximately 12:45, is mounted on the wall to the right of the screen. In the background right, a mobile whiteboard on wheels and a wall-mounted sink unit are partially visible. The central focus is a large, wall-mounted flat-screen display, presenting a blue-gridded graph. The graph's y-axis is labeled "Preis in EUR" (Price in EUR) with values ranging from 0.00€ to 5.00€, and its x-axis is labeled "Menge in Stück" (Quantity in Pieces). Two distinct curves are drawn: an upward-sloping pink line identified as "Angebotskurve" (Supply Curve) and a downward-sloping green line labeled "Nachfragekurve" (Demand Curve). The intersection point of these curves, marked with a circle, is labeled "GP" (Gleichgewichtspreis - Equilibrium Price) at approximately 2.50€. Shaded areas on the graph denote "Angebotsüberhang" (Supply Surplus) above the equilibrium and "Nachfrageüberhang" (Demand Surplus) below. An hourglass icon is present in the top-left corner of the display. In the foreground, a white table is arranged with various items. On the left, a black computer monitor is visible, with a white keyboard partially exposed to its left. An ELMO brand document camera, light-colored with a flexible neck, stands prominently in the center foreground, aimed towards the screen. Several cables are connected to its base. Immediately in front of the document camera, an open pink pencil case filled with colored pens and pencils is positioned alongside a small orange juice bottle labeled "Punkt". To the right, the table holds multiple stacked ring binders, some white and some green, along with notebooks and loose pens. A dark chair with a circular cut-out in its backrest is situated behind the table, in front of the large display. No individuals are present in the scene.
