    Answer: $8470

    Step-by-step explanation:

    To solve this, you can substitute 4 for x:

    [tex]f(x) = 13500*.89^4\\f(x) = 13500*0.6274\\f(x) = 8470[/tex]

    Mikayla’s scooter is worth around $8470 after 4 years.

    It was originally worth 13,500 dollars and depreciated by 11% every year.
