Answer:
The average rate of change is -0.034 which means that the decrease is -0.034 in the cost of per print per year
Step-by-step explanation:
Given that
Price of print in 2002 = p1 =$0.50
Price of print in 2013 = p2 =$0.13
y1 = 2002
y2 = 2013
The rate of change is given by the formula:
[tex]r = \frac{decrease}{run}[/tex]
Here decrease is the change in price and run is the difference in years.
Mathematically, it can be written as:
[tex]r = \frac{p_2-p_1}{y_2-y_1}[/tex]
Putting the values
[tex]r =\frac{0.13-0.50}{2013-2002}\\r = \frac{-0.37}{11}\\r =-0.0336\\r = -0.034[/tex]
Hence,
The average rate of change is -0.034 which means that the decrease is -0.034 in the cost of per print per year
