Question 988345: Dave is doing an experiment with a type of bacteria that he assumes divides exactly every 30 minutes. He begins at 8:00am with 10 bacteria in a petri dish and waits for 3 hours. At 11:00am he decides this is too large of a sample and adds chemical A to the dish, which kills half of the bacteria almost immediately. The remaining bacteria continue to grow in the same way. At noon, he adds chemical B to observe its effects. After observing the bacteria for two hours, he observes that chemical B seems to have cut the growth rate in half.
