The graph illustrates the amount of money Jakhongir and his students spent on valeryanka between 2020 and 2023. Overall, the data shows opposite spending trends for the two groups. Jakhongir’s expenses decreased steadily each year, while his students’ spending increased significantly over the same period.
In 2020, Jakhongir spent the highest amount at around 100 dollars, whereas his students spent only about 5 dollars. By 2021, Jakhongir still spent more than his students, but his expenses dropped slightly to about 95 dollars. His students, meanwhile, increased their spending to approximately 30 dollars. In 2022, this pattern continued as Jakhongir reduced his spending to 80 dollars, while his students spent around 40 dollars.
The most dramatic change occurred in 2023. Jakhongir’s spending fell sharply to just 20 dollars, which is his lowest value on the chart. In contrast, his students’ spending rose rapidly to nearly 100 dollars, becoming the highest figure for them across all years. This opposite trend suggests that while Jakhongir relied less on valeryanka over time, his students increasingly depended on it. The graph clearly highlights a shift in behavior, showing how the students eventually spent more than their instructor by a wide margin.
