Solution:

Given that the initial cost price of the jewelry is $2,200.

The rate at which it decreases each year is 12%.

Thus, the exponential decay function is;

$\begin{gathered} y(t)=2200(1-0.12)^t \\ \\ \text{ Where }t\text{ is the time in years.} \end{gathered}$

The graph of the function is;

From the graph;
