[Question]Eden, Mary and Iris gather sand to fill their sandbox. Eden carried 4 buckets of sand. Mary carried 3 more buckets of sand than Eden. Iris carried 1 less bucket of sand than Mary. If each bucket contains 2 pounds of sand, how many pounds of sand did they collect in total?
[Answer]Mary carried 4 + 3 = 7 buckets of sand. Iris carried 7 – 1 = 6 buckets of sand. All together, they carried 4 + 7 + 6 = 17 buckets of sand. The sand weighed a total of 17 * 2 = 34 pounds. The answer is 34.
Q: If there are two pennies in each of the twelve compartments of Roshesmina's piggy bank and she adds 6 more pennies to each compartment, calculate the total number of pennies she has?
A: In each compartment, there are two pennies, and when she adds 6 pennies to each compartment, one compartment will have 6 + 2 = 8 pennies. If there are 12 compartments, and each compartment now contains 8 pennies, there are a total of 12 * 8 = 96 pennies in all the compartments. The answer is 96.
Question: The ratio of coins that Elsa has to that which Amalie has is 10:45. If the total number of coins they have is 440, and Amalie spends 3/4 of what she has on toys, how many will she remain with?
Answer: The total ratio of the coins they both have is 10 + 45 = 55. The fraction of the ratio representing the number of coins that Amalie has is 45 / 55, and since the total number of coins they both have is 440, Amalie has 45 / 55 * 440 = 360 coins. When Amalie spends 3 / 4 of what she has, she parts with 3 / 4 * 360 = 270 coins. She still has 360 coins - 270 coins = 90 coins. The answer is 90.
[Question]A library has 7 rectangular tables and the remaining tables will be square tables. A rectangular table seats 10 pupils while a square table seats 4 pupils. How many square tables are needed so that 90 pupils can read at the same time?
[Answer]The rectangular tables seat 7 * 10 = 70 pupils. The square tables will seat 90 - 70 = 20 pupils. The library needs 20 / 4 = 5 square tables. The answer is 5.
Q: Joseph and his friends watched two movies in his house. The first movie is 1 hour and 30 minutes long while the second movie is 30 minutes longer than the first. Before the movies, they spent 10 minutes making popcorn and twice as long making fries. How long, in hours, did it take Joseph and his friends to cook and watch the movies?
A: The first movie was 60 + 30 = 90 minutes long since an hour has 60 minutes. The second movie was 90 + 30 = 120 minutes long. It took them a total of 90 + 120 = 210 minutes to watch the two movies. It took them 10 x 2 = 20 minutes to cook the fries. Thus, it took them a total of 10 + 20 = 30 minutes to cook. So, they spent 210 + 30 = 240 minutes watching the movies and cooking. In hours, this is equal to 240 / 60 = 4 hours. The answer is 4.
Question: Samantha’s last name has three fewer letters than Bobbie’s last name. If Bobbie took two letters off her last name, she would have a last name twice the length of Jamie’s. Jamie’s full name is Jamie Grey. How many letters are in Samantha’s last name?
Answer:
There are 4 letters in Jamie’s last name, so Bobbie’s name is 4 * 2 + 2 = 10 letters long. Samantha’s last name is 3 letters shorter than Bobbie’s, so there are 10 - 3 = 7 letters in Samantha’s last name. The answer is 7.
