Question: Minnie is making a playlist of songs for a party she will be throwing. She wants the playlist to be an hour long. She has added 16 three-minute songs to the playlist. How many four-minute songs does she have to add to make sure the playlist is an hour long?
Answer: An hour is equal to 60 minutes. Minnie has 16 * 3 = 48 minutes of songs already on the playlist. She has to fill 60 - 48 = 12 more minutes. Thus, she needs to add 12 / 4 = 3 four - minute songs. The answer is 3.
[Question]There are many CDs in the store. The rock and roll CDs are $5 each, the pop CDs are $10 each, the dance CDs are $3 each, and the country CDs are $7 each. Julia wants to buy 4 of each, but she only has 75 dollars. How much money is she short?
[Answer]Rock and Roll CDs will be 5 * 4 = 20 dollars. Pop CDs will be 10 * 4 = 40 dollars. Dance CDs will be 3 * 4 = 12 dollars. Country CDs will be 7 * 4 = 28 dollars. In total Julia would need 20 + 40 + 12 + 28 = 100 dollars. Julia is short 100 - 75 = 25 dollars. The answer is 25.
Q: Billy and George are picking dandelions. At first, Billy picks 36 and then George picks 1/3 as many as Billy. When they see the pile, they each decide to pick 10 more each. How many have they picked on average?
A: George picked at first 12 because 36 / 3 = 12. George picks 22 by the end because 12 + 10 = 22. Billy picks 66 by the end because 36 + 10 = 46. In total they picked 68 because 22 + 46 = 68. On average they picked 34 because 68 / 2 = 34. The answer is 34.
Question: Kimiko watches four YouTube videos. The first video is 2 minutes long, the second video is 4 minutes and 30 seconds, and the last two videos are equal in length. If she spends a total of 510 seconds watching YouTube, how many seconds long was each of the last two videos?
Answer: First convert the length of the first video to seconds: 2 minutes * 60 seconds / minute = 120 seconds. Then convert the length of the second video to seconds: 4 minutes * 60 seconds / minute + 30 seconds = 240 seconds + 30 seconds = 270 seconds. Now subtract the length of the first two videos from the total time Kimiko spent watching to find the combined length of the last two videos: 510 seconds - 120 seconds - 270 seconds = 120 seconds. Now divide the combined length by the number of videos to find each video's length: 120 seconds / 2 = 60 seconds. The answer is 60.
[Question]Mr. Bodhi is transporting some animals using a yacht across a river. He has 20 cows, 15 foxes and three times as many zebras as foxes. To balance the yacht to ensure a smooth sail across the river, the total number of animals in the yacht needs to be 100. If he decides to add sheep to the yacht to make the yacht sail-worthy, how many sheep did he add to the yacht?
[Answer]The number of cows and foxes in the yacht is 20 + 15 = 35. Mr. Bodhi also has three times as many zebras as foxes in the yacht, equal to 3 * 15 = 45 zebras. The number of animals in the yacht so far is 35 + 45 = 80. To balance the yacht, Mr. Bodhi needs to add 100 - 80 = 20 sheep. The answer is 20.
[Question]Marly is making soup. He adds 2 quarts of milk and three times as much chicken stock to 1 quart of pureed vegetables. Then he divides the soup into bags that can hold 3 quarts each. How many bags does he need?
[Answer]
First triple the amount of milk to find the amount of chicken stock: 2 quarts * 3 = 6 quarts. Then add all three quantities to find the total volume of the soup: 6 quarts + 2 quarts + 1 quart = 9 quarts. Finally, divide the number of quarts by the number of quarts per bag to find the number of bags needed: 9 quarts / 3 quarts / bag = 3 bags. The answer is 3.
