Extracted text: 5. The population of a rare breed of frog in a conservation area is decreasing. In this one conservation area there are only 60 left. The population of the frogs can be modeled by P= 60(0.8)' where P is the population of frogs and t is the time in years. a. How many frogs are there in 2 years? b. The population of frogs is decreasing. How many frogs are there if only a quarter of the original population is left? c. Write an exponential equation that can be used to determine when the population of the frog reaches a quarter of its original population (using your answer from part b).
