    Answer:

    $90

    Step-by-step explanation:

    Given data

    Price= $900

    Rate= 25%

    Time= 8 years

    Let us apply the compounding formula

    A= P(1-r)^t    >>>>note that the negative sign is because of the depreciation

    substitute

    A= 900(1-0.25)^8

    A= 900(0.75)^8

    A= 900*0.100

    A= $90

    Hence the value of the car after 8 years will be  $90
