16. Suppose you have a population of 300 butterflies. If the population experiences a net
growth of 12% in the following year, how many butterflies do you have?
17. Now suppose you have 300 eggs, but only 70% of those eggs become caterpillars, and
only 80% of the caterpillars become adult butterflies. How many butterflies do you have?
(For simplicity, assume that all butterflies survive to the next year in this example.)
18. Suppose you have a population of 150 butterflies, but a wildfire devastates the
population and only 24 butterflies survive. What percent does the colony decrease by?
