[Question]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?
[Answer]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.
Q: There are 250 books inside a library. On Tuesday, 120 books are taken out to be read by children. On Wednesday, 35 books are returned. On Thursday, another 15 books are withdrawn from the library. How many books are now in the library?
A: On Tuesday, 120 books were taken out 250 - 120 = 130 books. On Wednesday, 35 books were returned 130 + 35 = 165 books. On Thursday, 15 books were borrowed 165 - 15 = 150 books. The answer is 150.
Question: Matt buys a massager. At the lowest setting, it vibrates at 1600 vibrations per second. At the highest setting, it vibrates 60% faster. Matt uses it for 5 minutes at the highest setting. How many vibrations does he experience?
Answer: At the highest setting, it vibrates 1600 * .6 = 960 vibrations per second faster than the lowest setting. So it vibrates at 1600 + 960 = 2560 vibrations per second. Matt uses it for 5 minutes so that is 5 * 60 = 300 seconds. That means he experienced 2560 * 300 = 768,000 vibrations. The answer is 768000.
