Reasoning and answer: 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

The baseball glove was originally $30 and he agreed to take 20% off so 30 * .20 = $6.00 off. If you take the price of the glove and subtract the discount then $30 - $6 = $24.00. He sold 2 pair of shoes for $10 each so 2 * $10 = $20.00. He got $25 for the cards, $10 for the bat, $24.00 for the glove and $20 for the shoes so he made $25 + $10 + $24 + $20 = $79.00.
The answer: 79

Reasoning and answer: First find how many months the loans last: 20 years * 12 months / year = 240 months. Then divide the cost of the house by the number of payments to find the monthly payment before interest: $480,000 / 240 months = $2000 / month. Then do the same thing to find the monthly payment before interest on the trailer: $120,000 / 240 months = $500 / month. Then subtract the cost of the trailer payment from the cost of the house payment to find the difference: $2000 / month - $500 / month = $1500 / month.
The answer: 1500

Reasoning and answer: After half an hour, the number of balloons that had blown up is 1 / 5 * 200 = 40. The number of balloons that haven't blown up so far is 200 - 40 = 160. In the next hour, 2 * 40 = 80 balloons blow up. The number of balloons that haven't blown up now is 160 - 80 = 80.
The answer: 80
