There are initially 4000 bacteria per milliliter in a sample, and after 1 hour their concentration increases to 6000 bacteria per milliliter. Assume the bacteria grow exponentially, using the formula A=A0ekt. Use the given information to find k. Rewrite the formula so that the only unknown values are A and t. How many bacteria are there after 2.5 hours? After how long are there 8500 bacteria per milliliter?
