A bacteria culture started with a count of 480 at 8:00 A.M. and after t hours is expected to grow to f(t)=480(1/2)^t. Estimate the number of bacteria in the culture at noon the same day.
-------------
I assumed your posted "c/2" was really "1/2"
---------
From 8:00 to noon is 4 hours.
f(4) = 480(1/2)^4 = 480/16 = 30 bacteria
