What is the decrease in the consumption of goods from the year 1999 to 2000 as shown in the scatter plot?

To determine the decrease in the consumption of goods from 1999 to 2000, we need to compare the values of consumption in those two years on the scatter plot.

Let's assume the consumption of goods in 1999 is represented by point A on the scatter plot, and the consumption of goods in 2000 is represented by point B on the scatter plot.

We can see that the consumption of goods in 1999 is higher than the consumption of goods in 2000, as point A is above point B on the scatter plot.

To calculate the decrease in consumption, we need to subtract the consumption in 2000 from the consumption in 1999:

Decrease in consumption = Consumption in 1999 - Consumption in 2000

Therefore, the decrease in the consumption of goods from 1999 to 2000 is the difference between the y-coordinates of points A and B on the scatter plot.

The given context does not provide a scatter plot or any data on the consumption of goods. Therefore, I cannot extract the requested information.
