Answer:
Decay
Explanation:
Considering the model:
[Tex]A=1200(.85)^6[/tex]
0.85=1-0.15
Therefore, the model can be rewritten as:
[Tex]A=1200(1-0.15)^6[/tex]
This shows that the model decays by a common ratio of 0.15 or 15%.
In general, when the common ratio is less than 1, the model decays while whenever it is greater than one, there is exponential growth.
