Answer:


Step-by-step explanation:
The question is 
We let
, so the equation becomes:

Where 
By applying the quadratic formula, we arrive at:
Quadratic formula: 
Substituting yields:

We let
, thus x calculates to:

and

The solutions to the equation are
(rounded to 2 decimal places) and
(rounded to 2 decimal places)
The graph indicates that x never goes below 0. This means the point (-1,0) is not included in the graph. Therefore, D is the only valid option.
The initial value stands at 20,300, decreasing annually by 9.5%.
Given that it decreases by 9.5% each year based on the preceding amount, we can apply an exponential decay model.
A 9.5% reduction means multiplying by 91.5% every year.
We express this mathematically. Plugging in 11 years for t yields.
$7,671.18
