Answer:
second choice 12,000(0.9)ˣ
Explanation:
The equation for the value of the motorcycle can be modeled as follows
V = 12000(1- r)ˣ where r is the rate of decine
1- r must be less than 1 since the value is decreasing
We can eliminate the first and third choices which show the value as increasing.
The value of the motorcycle at x = 0 is 12,000
Therefore the correct choice is the second choice 12,000(0.9)ˣ
The last choice is wrong- it's showing the base price as 10,800
