user100 [1]

Answer:

(2) The motorcycle cost $12,000 when purchased.

Step-by-step explanation:

Since the equation is V(t) = 12,000(0.75)^t, a is 12,000.

This means that the original value was 12,000.

So, the motorcycle cost $12,000 when it was first purchased.

The correct answer is (2) The motorcycle cost $12,000 when purchased.
