2. There are 30 guinea pigs introduced into an ecosystem, and their population grows at a rate proportional to its size. In 2 years, the population grows to 85 guinea pigs. (a) Find a formula for the function P(t) that gives the population of guinea pigs at any time t measured in years. [5] [4] (b) Using your answer to part (a), determine how long it would take the guinea pig population to quadruple.
