Answer:

c $11,751

Explanation:

The function that models Alicia's car is


f(x) = 21000(0.93)^(x)

where x represents the number of years since she purchased the car.

We want to find the value of Alicia's car after 8 years.

We substitute x=8 into the formula to get:


f(8) = 21000(0.93)^(8)


f(8) = 21000(0.5596)


f(8) = 11751.218

We round to the nearest dollar to get:


f(8) =11751

The correct answer is C.
