Question: Brian loves watching animal videos online. He watches a 4-minute video of cats. He then watches a video twice as long as the cat video involving dogs. He finishes up his video watching for the day by watching a video on gorillas that's twice as long as the previous two videos combined. How many minutes does Brian spend watching animal videos?
Answer: Brian begins by watching a 4 - minute video, and since the second video is twice as long that means the second video is 4 * 2 = 8 minutes. The first two videos combined therefore for a 4 + 8 = 12 minute run time. Since the third video is twice as long as the first two videos put together, that means it is 12 * 2 = 24 minutes in length. The total length of time spent is therefore 24 + 12 = 36 minutes. The answer is 36.
[Question]If olivine has 5 more precious stones than agate and diamond has 11 more precious stones than olivine, how many precious stones do they have together if agate has 30 precious stones?
[Answer]Since Agate has 30 precious stones and Olivine has 5 more precious stones, then Olivine has 30 + 5 = 35 precious stones. The total number of stones Olivine and Agate has is 35 + 30 = 65. Diamond has 11 more precious stones than Olivine, who has 35 stones, meaning Diamond has 35 + 11 = 46 precious stones. In total, they all have 65 + 46 = 111 precious stones. The answer is 111.
Q: For every 1 year a human ages, a dog ages 7 years. When Max is 3, how much older, in dog years, will his 3-year-old dog be?
A: The 3 - year - old dog ages 7 years to one human year so he will technically be 3 * 7 = 21 years old in dog years. Max's dog will be 21 when Max turns 3 so the age difference is 21 - 3 = 18. The answer is 18.
Question: Nina has two pairs of shoes. She bought one of them for $22, and the second one was 50% more expensive. How much did Nina pay for both pairs of shoes?
Answer: The second pair of shoes was 50 / 100 * 22 = $11 more expensive. That means that the second pair's price was 22 + 11 = $33. So for both pairs of shoes, Nina paid 33 + 22 = $55. The answer is 55.
[Question]John has a donkey and an elephant. The elephant weighs 3 tons (a ton is 2000 pounds). The donkey weighs 90% less. What is their combined weight in pounds?
[Answer]The elephant weighs 3 * 2000 = 6000 pounds. The donkey weighs 6000 * .9 = 5400 pounds less. So the donkey weighs 6000 - 5400 = 600 pounds. That means the combined weight is 600 + 6000 = 6600 pounds. The answer is 6600.
