Answer the following question.
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?
Step-by-step reasoning process: 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 is 480.

Answer the following question.
Steve puts $100 into the bank. Each year he earns 10% interest on the money in the account. How much money will be in the bank after 2 years?
Step-by-step reasoning process: At the end of the first year, there will be $100 * (110 / 100) = $110 in the bank account. At the end of the second year, there will be $110 * (110 / 100) = $121.

Answer the following question.
Timmy plans to ride a skateboard ramp that is 50 feet high. He knows he needs to go 40 mph at the start to make it all the way to the top. He measures his speed on three trial runs and goes 36, 34, and 38 mph. How much faster does he have to go than his average speed to make it up the ramp?
Step-by-step reasoning process: His total speed from the trials is 108 because 36 + 34 + 38 = 108. His average speed was 36 mph because 108 / 3 = 36. He needs to go 4 mph faster to make it to the top because 40 - 36 = 4.
The answer is 4.

Answer the following question.
Grayson has 100 questions on a test. He answers some of the questions for 2 hours, taking two minutes for each answer, then realizes he doesn't know the rest of the questions. How many questions does Grayson leave unanswered when he submits his test?
Step-by-step reasoning process: Each hour contains 60 minutes, so after 2 hours he took 2 * 60 = 120 minutes. If each question takes two minutes, then he answered 120 / 2 = 60 questions. Unanswered questions is 100 - 60 = 40 questions.
The answer is 40.
