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

This is a trick question. 7 families had a parakeet.
