Reasoning and answer: Andrew’s guest bedroom took 8 - 2 = 6 wooden planks. His hallways took 2 * 4 = 8 planks. In two bedrooms, he ruined 3 planks each, so the bedrooms took an extra 3 * 2 = 6 planks. In all, he used 8 + 20 + 11 + 6 + 8 + 6 = 59 planks for his whole house. Andrew had 6 leftover planks, so he bought 59 + 6 = 65 wooden planks to start with.
The answer: 65

Question: Andrew installed hardwood flooring in his house. His bedroom took eight wooden planks, his living room took twenty planks, and his kitchen took eleven planks. The guest bedroom took two fewer planks than Andrew’s bedroom, and each of his two hallways took four planks. He accidentally ruined three planks in each bedroom by dragging furniture over them and had to replace them. He ended up with six leftover planks at the end. How many wooden planks did Andrew buy to start with?


Two cellphones cost $800 x 2 = $1600. The 5% discount amounts to $1600 x 5 / 100 = $80. So Miley paid $1600 - $80 = $1520.
The answer: 1520
Reverse engineering the question: Miley bought two cellphones for her parents. Each cellphone costs $800 but, since she is buying two units, she will receive a 5% discount for the total cost. How much did Miley pay?


Reasoning and answer: Half the pet - owners have a cat because 1 - 1 / 2 = 1 / 2. There are 60 pet owners because 30 / (1 / 2) = 60. The town has 100 citizens because 60 / .6 = 100.
The answer: 100

Question: In a town where 60% of the citizens own a pet, half own a dog and 30 own a cat. How many citizens are in the town?


Total number of candies is 200 / 2.5 = 80 candies. Let x be the number of cherry candies. There are 3 * x grape candies. There are 2 * 3 * x = 6 * x apple candies. x + 3 * x + 6 * x = 80. 10 * x = 80. x = 8. There are 8 * 3 = 24 grape candies.
The answer: 24
Reverse engineering the question: At the new store, there are 3 times as many grape candies as cherry candies, and 2 times as many apple candies as grape candies. All the candies cost $2.50 each. If the total cost of the candies is $200, how many grape candies does the store have?


Reasoning and answer: He sold 2 * 25 = 50 amulets. So he made 40 * 50 = $2000. The faire took 2000 * .1 = $200. So he kept 2000 - 200 = $1800. The amulets cost 50 * 30 = $1500 to make. So he had a profit of 1800 - 1500 = $300.
The answer: 300

Question: Dirk sells amulets at a Ren Faire. He sells for 2 days and each day he sells 25 amulets. Each amulet sells for 40 dollars and they cost him 30 dollars to make. If he has to give 10% of his revenue to the faire, how much profit did he make?


Reasoning and answer: He made $600.00 mowing yards, $250.00 for his birthday, $150.00 selling items and $150.00 doing odd jobs so he made 600 + 250 + 150 + 150 = $1,150.00. He made $1,150.00 and will save 40% so he saves 1150 * .40 = $460.00.
The answer: 460
