Q: Maisie and Donna dropped off flyers for a neighborhood clean-up day at houses around their neighborhood. Maisie walked down the shorter left street and dropped off 33 flyers. Donna took the long right street on her bicycle and dropped off five more than twice as many flyers as Maisie. How many flyers did Donna drop off?
A: Twice as many flyers as Maisie is 33 * 2 = 66 flyers. Donna dropped off five more than that, so she dropped off 66 + 5 = 71 flyers. The answer is 71.
Question: Sam memorized six more digits of pi than Carlos memorized. Mina memorized six times as many digits of pi as Carlos memorized. If Mina memorized 24 digits of pi, how many digits did Sam memorize?
Answer: Carlos memorized 24 / 6 = 4 digits of pi. Sam memorized 4 + 6 = 10 digits of pi. The answer is 10.
[Question]Whitney bought 9 books about whales and 7 books about fish. She also bought 3 magazines. Each book cost $11 and each magazine cost $1. How much did Whitney spend in all?
[Answer]The total number of books is 9 books + 7 books = 16 books. The cost of the books is $11 / book 16 books = $176. The cost of the magazines is $1 / magazine 3 magazines = $3. Whitney spent $3 + $176 = $179 in all. The answer is 179.
Q: John decided to start rowing around a square lake. Each side of the lake is 15 miles. Jake can row at twice the speed he can swim. It takes him 20 minutes to swim 1 mile. How long, in hours, does it take to row the lake?
A: The perimeter of the lake is 4 * 15 = 60 miles. He swims at a speed of 60 / 20 = 3 mph. So he rows at a speed of 3 * 2 = 6 mph. That means it takes him 60 / 6 = 10 hours to row around the lake. The answer is 10.
Question: Joel is picking peppers from his garden. He picks 7 on Sunday, 12 on Monday, 14 on Tuesday, 12 on Wednesday, 5 on Thursday, 18 on Friday and 12 on Saturday. He knows that in his garden 20% of the peppers are hot and the rest are not. How many non-hot peppers did he pick?
Answer: He picked 80 peppers because 7 + 12 + 14 + 12 + 5 + 18 + 12 = 80. 80% of the peppers are not hot because 100 - 20 = 80. He picked 64 non - hot peppers because 80 x .8 = 64. The answer is 64.
Q: Hasan is packing up his apartment because he's moving across the country for a new job. He needs to ship several boxes to his new home. The movers have asked that Hasan avoid putting more than a certain weight in pounds in any cardboard box. The moving company has helpfully provided Hasan with a digital scale that will alert him if a package is too heavy. Hasan is in the kitchen, and he fills a cardboard box with 38 dinner plates. When he checks the box, the scale reports his box is too heavy. Hasan knows each of his plates weighs 10 ounces. He removes a single plate from the box and checks the movers' scale again. The scale reports his box is still too heavy. Hasan repeats the process again and again. When he has removed enough plates, the movers' scale shows the box is now an acceptable weight for shipping. Hasan deduces that each shipping box can hold 20 pounds before the scale says the box is too heavy. How many plates did Hasan need to remove from the shipping box?
A:
Let x be the number of plates removed from the box. Hasan figured out the movers' weight limit was 20 pounds. Since a pound is equal to 16 ounces, each box can hold 20 * 16, or 320 ounces. Each plate weighs 10 ounces, so the weight of the plates in the box after Hasan removes enough plates to satisfy the movers' weight limit is (38 - x) * 10 ounces. Since these two values are equal, we can write the equation (38 - x) * 10 = 320. Dividing both sides by 10 leaves 38 - x = 32. Adding x to both sides gives 38 x + x = 32 + x, or, 38 = 32 + x. Subtracting 32 from both sides gives the value of x, which is the number of plates removed from the box, 38 - 32 = 32 + x 32, or, 6 = x. The answer is 6.
