1) An endangered species of fish has a population that is DECREASING exponentially (A=Aoe^kt). The population 5 years ago was 1900. Today, Only 1100 of the fish are alive.

a) Write an equation that models the decay of the population A(T)

b) Once the population drops below 100, the situation will be irreversible.

when will this happend, according to the model?(round to the nearest whole year)
