A culture of bacteria in a petri dish is doubling every hour. If there are 100 bacteria at time t=0, how many bacteria will there be in 12 hours?

Putting this information into the exponential growth formula gets you the equation y=100(2^x) where x equals the number of hours. Plugging in 12 for x, you get 409600.

. A lab is growing bacteria in a culture dish. The amount of bacteria in the dish doubles every 4 hours. Initially, there are 900 bacteria in the dish. How many are in the dish after 12 hours?
