Question and rationale: The question is: Jerry finds six hawk feathers and 17 times as many eagle feathers as hawk feathers. If he gives 10 feathers to his sister and sells half the remaining feathers, how many does he have left?
Step-by-step reasoning process: First find how many eagle feathers he found: 17 * 6 feathers = 102 feathers. Then add the number of hawk feathers he found: 102 feathers + 6 feathers = 108 feathers. Then subtract the number of feathers Jerry gave to his sister: 108 feathers - 10 feathers = 98 feathers. Then divide that number by 2 to find how many feathers Jerry has left: 98 feathers / 2 = 49 feathers.

Question and rationale: The question is: Juanico is 4 years less than half the age of Gladys. If Gladys will be 40 years old ten years from now, calculate Juanico's age 30 years from now.
Step-by-step reasoning process: If Gladys will be 40 years old ten years from now, she is 40 - 10 = 30 years old currently. Juanico is 4 years less than half the age of Gladys, meaning he is 4 years younger than 1 / 2 * 30 = 15 years. Juanico's age is 15 - 4 = 11 years. Juanico's age 30 years from now will be 30 + 11 = 41 years.

Question and rationale: The question is: Jill has a difficult test to study for. She decides to study one day for 2 hours. The next day she doubles this amount, and the day after that she studies one hour less than the previous day. How many minutes does Jill study over the 3 days?
Step-by-step reasoning process: First, we need to determine how many hours Jill studied in total. To find this out, we begin by performing 2 * 2 = 4 hours spent on day two, double what she spent on day 1. Next, we perform 4 - 1 = 3 hours to determine the amount she studied on the third day. We then add 2 + 4 + 3 = 9 hours spent in total across 3 days. Since there are 60 minutes in an hour, she studied 9 * 60 = 540 minutes in total.

Question and rationale:
The question is: John decided to buy 10 pins for himself. They are normally $20 each but they were on sale for 15% off. How much did he spend on pins?
Step-by-step reasoning process: The sell reduced the price of each pin by 20 * .15 = $3. So he paid 20 - 3 = $17 per pin. So the total cost was 17 * 10 = $170.
