Anna has been studying a type of bacteria that triples every month. originally, there were 4 bacterial cells. she wants to know how many there will be after 15 months. which equation should she use? a) a15 = 4(3)(15) b) a15 = 4(3)15 c) a15 = 4(3)15 − 1 d) a15 = 4(3)(15 − 1)

As per the given information;

Bacteria triples every month.

Originally, there were 4 bacterial cells.

We are suppose to find how many there will be after 15 months.

Hence we can say , the number of bacteria after n month can be given using the exponential growth function

So number of bacteria after 15 month will be

because its not ur topic and its not for is for homework not that.

answer: this is not a question
