[Question]Cole wants to fence his backyard on three sides. His backyard is 9 feet along the sides and 18 feet along the back. The neighbor behind him agreed to pay for half of their shared side of his fence, and the neighbor on his left agreed to pay for a third of their shared side. Fencing costs $3 per foot. How much does Cole have to pay for the fence?
[Answer]Cole has to pay 3 * 9 = $27 for one side of the side fence. For the shared left fence, he has to pay two - thirds of 27, so he has to pay 27 * 2 / 3 = $18. The shared back fence will cost 3 * 18 = $54. He has to pay for half the back fence, so it will cost 54 / 2 = $27. Thus, Cole has to pay 18 + 27 + 27 = $72 for the fence. The answer is 72.

Question: Mr. Langsley commutes to work every day by bus. The bus picks him up at 6:00 a.m. and takes forty minutes to arrive at the first station. If Mr. Langsley arrives at work at 9:00 a.m., what's the total time taken in minutes from the first station to Mr. Langsley's workplace?
Answer: The total time taken for the whole journey is 9:00 - 6:00 = 3 hours. The total time taken in minutes is 3 * 60 = 180 minutes. If it takes 40 minutes to reach the first station, then the rest of the journey takes 180 - 40 = 140 minutes. The answer is 140.
[Question]William read 6 books last month and Brad read thrice as many books as William did. This month, in an effort to catch up, Williams read twice as much as Brad, who read 8 books. Who has read more across the two months, and by how much?
[Answer]Last month Brad read thrice 6 books for a total of 3 * 6 = 18 books. This month Williams read twice 8 books for a total of 2 * 8 = 16 books. Across the 2 months Brad has read 18 + 8 = 26 books. Across the 2 months William has read 6 + 16 = 22 books. Brad has read 26 - 22 = 4 more books. The answer is 4.
Q: A store sold a certain brand of jeans for $40. They only have few pairs of jeans left so they decided to give 10% discount on every two pairs of jeans bought by a customer at any one time. How much will a customer pay for 3 pairs of jeans?
A: Two pairs of jeans cost $40 x 2 = $80. A discount of $80 x 10 / 100 = $8 will be given for this. Hence, the cost of two pairs of jeans will now be $80 - $8 = $72. Therefore, the customer will pay $72 + $40 = $112 for the three pairs of jeans. The answer is 112.
