    Answer:

    V(t) = 25000 * (0.815)^t

    The depreciation from year 3 to year 4 was $2503.71

    Step-by-step explanation:

    We can model V(t) as an exponencial function:

    V(t) = Vo * (1+r)^t

    Where Vo is the inicial value of the car, r is the depreciation rate and t is the amount of years.

    We have that Vo = 25000, r = -18.5% = -0.185, so:

    V(t) = 25000 * (1-0.185)^t

    V(t) = 25000 * (0.815)^t

    In year 3, we have:

    V(3) = 25000 * (0.815)^3 = 13533.58

    In year 4, we have:

    V(4) = 25000 * (0.815)^4 = 11029.87

    The depreciation from year 3 to year 4 was:

    V(3) – V(4) = 13533.58 – 11029.87 = $2503.71
