25% of his pets are bunnies because 100% - 50% - 25% = 25%. He has 9 bunnies because 36 x .25 = 9.
The answer: 9
Reverse engineering the question: Michael has 36 pets. 25% of them are dogs, 50% are cats, and the rest are bunnies. How many bunnies does he have?
Reasoning and answer: George picked at first 12 because 36 / 3 = 12. George picks 22 by the end because 12 + 10 = 22. Billy picks 66 by the end because 36 + 10 = 46. In total they picked 68 because 22 + 46 = 68. On average they picked 34 because 68 / 2 = 34.
The answer: 34
What was the question?
Question: Billy and George are picking dandelions. At first, Billy picks 36 and then George picks 1/3 as many as Billy. When they see the pile, they each decide to pick 10 more each. How many have they picked on average?
They sold 40 erasers because 20 x 2 = 40. Therefore 20(Pencil Price) + (1 / 2)(40 x Pencil Price) = 80. Therefore 40(Pencil Price) = 80. Therefore (Pencil Price) equals 2 because 80 / 40 = 2. An eraser costs $1 because 2 / 2 = 1.
The answer: 1
Reverse engineering the question: A store sells pencils and erasers. It has a rule that for every pencil you buy, you must buy 2 erasers which cost 1/2 the price of the pencils. If they sold 20 pencils and earned $80, how much do erasers cost?
Reasoning and answer: Tommy has 40 pennies because 10 x 4 = 40. Tommy has 50 dimes because 40 + 10 = 50. Tommy has 100 nickels because 50 x 2 = 100.
The answer: 100
What was the question?
Question: Tommy is looking at his change collection. He has 10 more dimes than pennies. He has twice as many nickels as dimes. He has 4 quarters. He has 10 times as many pennies as quarters. How many nickels does he have?
Let X be the age of Cooper. So Dante is X * 2 years old and Maria is X * 2 + 1 year old. The sum of Cooper's, Dante's, and Maria's ages is X + (X * 2) + (X * 2 + 1) = 31. Combining like terms, we get X * 5 + 1 = 31. Subtracting one from both sides, we get X * 5 = 30. Dividing both sides by 5, we get X = 6 years old.
The answer: 6
Reverse engineering the question: The sum of Cooper's, Dante's, and Maria's ages is 31. Dante is twice as old as Cooper. Maria is one year older than Dante. How old is Cooper?
Each of Tom's visits was 200 * .7 = $140 cheaper. So he paid $200 - $140 = $60 per visit. That means he paid $60 * 2 = $120. So he saved $200 - $120 = $80.
The answer: 80
Reverse engineering the question:
Tom cannot afford a normal doctor, so he goes to a discount clinic that is 70% cheaper. It takes two visits, though, instead of 1. A normal doctor charges $200 for a visit. How much money does he save?
