Question

Funny is studying a population of frogs. She determines that the population is decreasing at an average rate of 3% per year. When she began her study, the frog population was estimated at 1,200. Which function represents the frig population after years?

Answer 1

Each year the frog population is multiplied by (1-3%) = 97% = 0.97. The function that represents the frog population can be written as
.. p(t) = 1200*0.97^t
