Question: Barry goes to a shop to buy a shirt he'd been admiring for quite some time. He tells the attendant that it's his birthday so she decides to give him a 15% special discount. The price tag on the shirt says $80. How much is he supposed to pay now, considering the special discount?
Answer: 15% of $80 = (15 / 100) * $80 = $12. The dollar amount of the discount is $12 so he is supposed to pay just $80 - $12 = $68. The answer is 68.

Question: The distance between Arizona and New York is around 2,000 miles by plane. The distance between the 2 different US states increases by 40% if someone decides to drive instead of flying. Missouri is midway between Arizona and New York. How far away is Missouri from New York if someone decides to go by car?
Answer: The distance between Arizona and New York is 2,000 miles by plane. The distance between Arizona and New York is 40% greater by car, which is 40% * 2,000 = 800 miles. This results in a total of 2,000 + 800 = 2,800 miles between Arizona and New York by car. If Missouri is in the middle of the way between Arizona and New York, someone would drive half of the distance to go from Missouri to New York, which is 2,800 / 2 = 1,400. The answer is 1400.

Question: Jill can run up a hill at 9 feet/second and down a hill at 12 feet/second. How long does it take her to run up and down a 900 foot hill?
Answer: First find the time it takes Jill to run up the hill: 900 feet / 9 feet / second = 100 seconds. Then find the time it takes Jill to run down the hill: 900 feet / 12 feet / second = 75 seconds. Then add the two times to find Jill's total time: 100 seconds + 75 seconds = 175 seconds. The answer is 175.

Question: Mimi has decided to start going to the gym again. Over the weekend, she spent $8,000 on athletic sneakers and clothes. She spent thrice as much on Nike sneakers as she did on Adidas. What she spent on Adidas was 1/5 the cost of Skechers. If Mimi's Adidas sneakers purchase was $600, what amount did she spend on clothes?
Answer:
The Adidas purchase was 1 / 5 that of Skechers, therefore the Skechers cost 5 * 600 = 3000 dollars. Spending three times the cost of Adidas on Nike sneakers translates to 3 * 600 = 1800 dollars. All together, the three athletic - sneaker purchases cost Mimi 600 + 1800 + 3000 = 5400 dollars. Subtracting the amount spent on athletic sneakers from the total spent gives 8000 - 5400 = 2600 dollars. Mimi therefore spent 2600 dollars on clothes. The answer is 2600.
