Milly is making feather boas for her dance team. Each flamingo has 20 tail feathers, and it's only safe to pluck 25% of their tail feathers at one time. If Milly needs to make 12 boas, and each boa has 200 feathers, how many flamingoes does she need to harvest? Let's answer step by step:
First find the number of feathers Milly can get from one flamingo: 20 feathers * 25% = 5 feathers. Then find how many feathers she needs total: 12 boas * 200 feathers / boa = 2400 feathers. Then divide the number of feathers she needs by the number of feathers per flamingo to find the number of flamingoes she needs to harvest: 2400 feathers / 5 feathers / flamingo = 480 flamingoes. The answer: 480.
