Bacteria culture started with a count of 480 at 8:00am and after t hours is expected to grow to f(t)=480(3/2)^t. Estimate the number the number of bacteria in the culture at noon the same day. My answer is 2430, thanks for checking my answer.

Hello, kwtolley!
"Noon the same day" means $\displaystyle t = 4$.Bacteria culture started with a count of 480 at 8:00am and after $\displaystyle t$ hours
is expected to grow to: $\displaystyle f(t)\,=\,480\left(\frac{3}{2}\right)^t$
Estimate the number the number of bacteria in the culture at noon the same day.
My answer is $\displaystyle 2430$.
$\displaystyle f(4)\;= \;480\left(\frac{3}{2}\right)^4 \;= \;2430$ . . . Good for you!
