The amount A(t) of atmospheric pollutants in a certain mountain valley grown according to a natural growth model in such a way that the amount triples every 12 years. Initially the valley contains 8 pu ( pollutant units).

It is considered dangerous to live in the valley once the level reaches 100 pu. how long will it take before it is considered dangerous to live in this mountain valley ?
