    Hello, kwtolley!

    Bacteria culture started with a count of 480 at 8:00am and after t hours
    is expected to grow to: f(t)\,=\,480\left(\frac{3}{2}\right)^t

    Estimate the number the number of bacteria in the culture at noon the same day.

    My answer is 2430.
    "Noon the same day" means t = 4.

    f(4)\;= \;480\left(\frac{3}{2}\right)^4 \;= \;2430 . . . Good for you!
