[Question]Stan can type 50 words per minute. He needs to write a 5-page paper. Each page will contain 400 words. Each hour that he types he needs to drink 15 ounces of water. How much water does he need to drink while writing his paper?
[Answer]Stan needs to write 2,000 words because 5 x 400 = 2,000. This will take him 40 minutes because 2,000 / 50 = 40. He drinks 1 / 4 an ounce per minute because 15 / 60 = 1 / 4. He will drink 10 ounces of water while writing the paper because 40 x (1 / 4) = 10. The answer is 10.
Q: One necklace is worth $34. Bob decided to buy one for his wife. But, he also bought a book, which is $5 more expensive than the necklace. Before he went shopping, Bob set a limit and decided not to spend more than $70. How many dollars over the "limit" did Bob spend?
A: The book is $5 more expensive than the necklace, which means the book costs 34 + 5 = $39. Both products which Bob wants to buy cost in total 39 + 34 = $73. So Bob will spend 73 - 70 = $3 over the limit. The answer is 3.
Question: In a Zoo, there are different animals. There are 5 giraffes and twice as many penguins. Penguins make up 20% of all the animals in the Zoo. How many elephants are there in the Zoo if they make up 4% of all the animals?
Answer: There are twice as many penguins as giraffes, so there are 5 * 2 = 10 penguins. The penguins make up 20% of all animals, so there are 100 / 20 * 10 = 50 animals in the whole Zoo. 4% of animals are elephants, so there are 4 / 100 * 50 = 2 elephants at the Zoo. The answer is 2.
[Question]Piazzanos Pizzeria has a buy-1-get-1-free special on triple cheese pizzas, and a buy-2-get-1-free special on meat lovers pizzas. If the standard price for a pizza is $5, how much does it cost, in dollars, to purchase 10 triple cheese and 9 meat lovers pizzas using the special pricing?
[Answer]Using buy - 1 - get - 1 - free pricing, it costs 1 * $5 = $5 to buy 2 triple cheese pizzas. At $5 per 2 pizzas, it costs $5 / 2 = $2.5 per triple cheese pizza. Using buy - 2 - get - 1 - free pricing, it costs 2 * $5 = $10 to buy 3 meat lovers pizzas. At $10 per three pizzas, it cost $10 / 3 = $3 and $1 / 3 per meat lovers pizza. With the buy - 1 - get - 1 - free pricing, 10 triple cheese pizzas are 10 * $2.5 = $25. With the buy - 2 - get - 1 - free pricing, 9 meat lovers pizzas are 9 * ($3 + $1 / 3) = $30. In total, for 10 triple cheese and 9 meat lovers pizzas, it will cost $25 + $30 = $55. The answer is 55.
