Question

Find the average rate of change in cigarette consumption for the years shown during which consumption was increasing. Round to one decimal place, if

necessary.

Answer 1

1.875

Explanation:

To find the average rate of change, we will draw a line from the initial point (1850) to the final point (2010, 300B) as shown in the image provided

Now, we just have to find the slope of this line

We know that slope = Rise /Run

from the image, we know that the rise = 300 and the run is 160

Hence,

Slope = 300 / 160

Slope = 1.875

Therefore,

The average rate of change of cigarette consumption is 1.875 Billion
