(06.05 MC) Iris is a botanist who works for a garden that many tourists visit. The function f(s) = 2s + 25 represents the number of flowers that bloomed, where s is the number of seeds she planted. The function s(w) = 25w represents the number of seeds she plants per week, where w represents the number of weeks. Part A: Write a composite function that represents how many flowers Iris can expect to bloom over a certain number of weeks. (4 points) Part B: What are the units of measurement for the composite function in Part A? (2 points) Part C: Evaluate the composite function in Part A for 30 weeks. (4 points)
