[Question]Stacy went to a store to buy some pairs of shorts. Each pair normally cost $10, but there's a discount of 10% on the total cost for people who purchase 3 or more pairs at once. How much can she save by buying 3 pairs at once as opposed to purchasing them individually at different times?
[Answer]Without the discount, each pair cost $10 so 3 pairs cost 3 * $10 = $30. With a discount of 10% on the total cost, she can pay only $30 - ($30 * (10 / 100)) = $27. By buying 3 at once in order to get the discount, she can save $30 - $27 = $3. The answer is 3.
Q: The P.T.O. decided to provide shirts for the elementary students for track and field day. Each grade was given a different color. 101 Kindergartners wore orange shirts that cost $5.80 each. 113 first graders wore yellow shirts that cost $5 each. 107 second graders wore blue shirts that cost $5.60 each. 108 third graders wore green shirts that cost $5.25 each. How much did the P.T.O. spend on shirts for field day?
A: The cost for 101 Kindergarten shirts x $5.80 = $585.80. The cost for 113 first grade shirts x $5 = $565. The cost for 107 second grade shirts x $5.60 = $599.20. The cost for 108 third grade shirts x $5.25 = $567. The total cost of the shirts was $585.80 + $565 + $599.20 + $567 = $2,317. The answer is 2317.
Question: The price of a book was $400. If the book's price is decreased by 15% and then increased by 40%, what is the final price of the book?
Answer: When the price of the book is decreased by 15%, the total price decrease is 15 / 100 * $400 = $60. The new price of the book becomes $400 - $60 = $340. The price of the book is then increased by 40 / 100 * 340 = $136. The final price of the book is $340 + $136 = $476. The answer is 476.
[Question]Marissa is serving her kids lunch. Each kid gets a burger with 400 calories and 5 carrot sticks with 20 calories each, and some cookies with 50 calories each. Marissa wants each kid to eat a total of 750 calories for lunch. How many cookies does each kid get?
[Answer]First figure out how many total calories come from the carrots by multiplying the calories per carrot by the number of carrots: 20 calories / carrot * 5 carrots = 100 calories. Then subtract the calories the kids have already eaten from the goal number of calories to find out how many more total calories they should eat: 750 calories - 400 calories - 100 calories = 250 calories. Then divide the total number of calories by the calories per cookie to find the number of cookies each kid gets: 250 calories / 50 calories / cookie = 5 cookies. The answer is 5.
[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?
[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 is 300.
