Data:

Initial price: $67.000

Price decrease: .30 each year t

The general form of a model of exponential decrease is:

f(t)=p_0(1-r)^t

Where P0 is the initial price, r is the rate of decrease and t the number of periods.

Then, for the given situation you get the next equation:

\begin{gathered} f(t)=67000(1-0.30)^t \\ f(t)=67000(.70)^t \end{gathered}Then, the answer is the option D.
