Hello, kwtolley!

Quote:

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!
