$N(d)=115(0.90)^{d}$
The function $N$ defined above can be used to model the number of species of brachiopods at various ocean depths $d$, where $d$ is in hundreds of meters. Which of the following does the model predict?
Difficulty: Medium
A:
For every increase in depth by 1 meter, the number of brachiopod species decreases by 115.
B:
For every increase in depth by 1 meter, the number of brachiopod species decreases by 10%.
C:
For every increase in depth by 100 meters, the number of brachiopod species decreases by 115.
D:
For every increase in depth by 100 meters, the number of brachiopod species decreases by 10%.
