Question: After shearing her 200 sheep, Azalea paid the shearer who had come to help her with the work $2000 for his job. Each of the sheared sheep produced 10 pounds of wool. If Ms. Azalea sold a pound of wool at $20, how much profit did she make from the produce of her sheep farm?
Answer: Since there were 200 sheep, the amount of wool Azalea got after the shearing of the sheep is 200 * 10 = 2000 pounds of wool. If she sold one pound of wool at $20, the total amount of money she made from the sheep farm is 2000 * $20 = $40000. Her profit, which is $2000 less the amount of money she paid to the shearer, is $40000 - $2000 = 38000. The answer is 38000.
[Question]Baez has 25 marbles. She loses 20% of them one day. Then a friend sees her and gives her double the amount that Baez has after she lost them. How many marbles does Baez end up with?
[Answer]She loses 5 marbles because 25 x .2 = 5. She has 20 marbles after this because 25 - 5 = 20. Her friend gives her 40 marbles because 20 x 2 = 40. Adding those marbles to the 20 she had before, she ends up with 40 marbles + 20 marbles = 60 marbles. The answer is 60.
Q: If you take the fastest speed of a rabbit and double it, add 4 to that then double it again you get 188. How fast is the rabbit?
A: You doubled a number to get 188 so in reverse, you would divide by 2 so 188 / 2 = 94. You added 4 to this number and in reverse, you would subtract by 4 so 94 - 4 = 90. You doubled a number to get 90 so in reverse you would divide by 2 so 90 / 2 = 45 is the fastest speed. The answer is 45.
Question: A gecko lays 30 eggs per year. 20 percent of them are infertile, and a third of the remaining eggs will not hatch due to calcification issues. How many eggs actually hatch?
Answer: Infertile:30(.20) = 6. 30 - 6 = 24 eggs remain. Calcification Issues:24(1 / 3) = 8. 24 - 8 = 16 eggs that will hatch. The answer is 16.
[Question]Ten percent less than twice the total number of students present in the science class yesterday have attended class today. If there were 70 students in the class yesterday and 30 students are absent today, calculate the number of students registered for the course.
[Answer]Twice the number of students present in the science class yesterday is 70 * 2 = 140. Ten percent less than twice the number of students present in the class yesterday means there are 10 / 100 * 140 = 14 fewer students than twice the number present yesterday. The number of students present in the science class today is 140 - 14 = 126. If the total number of registered students for the course who are absent today is 30, a full class of the science course has 126 + 30 = 156 students. The answer is 156.

Three years ago, his sons were 16 - 3 = 13 years old. Three years ago, Beau was 13 + 13 + 13 = 39 years old. Today, Beau is 39 + 3 = 42 years old. The answer is 42.
