Answer:
The answer is below
Step-by-step explanation:
The graph used to estimate the consumption (in billions) in the United States for the years 1900 to 2007 is attached.
The year is plotted on the x axis and the number of cigarettes is on the y axis. To estimate the number of cigarattes smoked in year 2000, we have to find the y coordinate that corresponds to an x coordinate of 2000. This is done by drawing a line vertically to touch the graph from the point 2000 on the x axis. The point it touches the graph is then traced to the y axis to get the consumption as shown in the graph attached.
From the graph the number of cigarettes smoked in 2000 is about 420 billion cigarettes
