Q: Hortense loves daisies and sunflowers. She planted 25 daisy seeds and 25 sunflower seeds in her flower bed. If 60% of the daisy seeds germinate, and 80% of the sunflower seeds germinate, and 80% of the resulting plants produce flowers, how many plants will she grow that produce flowers?
A: At a germination rate of 60%, 25 seeds will yield 60 / 100 * 25 = 15 plants. At a germination rate of 80%, 25 seeds will yield 80 / 100 * 25 = 20 plants. In total, she will have grown 15 + 20 = 35 plants. If 80% of the plants developed flowers, then she will have grown (80 / 100) * 35 = 28 plants that produce flowers. The answer is 28.
