[Answer]Lilibeth picks 6 x 50 = 300 strawberries. There are 1 + 3 = 4 of them who are picking strawberries. Therefore, they pick a total of 300 x 4 = 1200 strawberries. The answer is 1200.
Q: Tony has two fish. Every year, his parents buy him two more, but one of them dies. How many fish will he have in five years?
A: Each year Tony has one more fish than before because 2 - 1 = 1. In five years, he will have 5 more fish because 5 x 1 = 5. In five years he will have 7 fish because 2 + 5 = 7. The answer is 7.
Question: Danny has 3 bottles of soda. He drinks 90% of one bottle and gives 70% of the other two bottles to his friends. How much soda does Danny have left, expressed as a percentage of a bottle?
Answer: First find how much soda Danny drank: 1 bottle * .9 = .9 bottles. Then find how much soda Danny gave to his friends: 2 friends * 1 bottle / friend * .7 = 1.4 bottles. Now subtract the soda drunk and given away to find the remaining amount of soda: 3 bottles - .9 bottles - 1.4 bottles = .7 bottles * 100% = 70%. The answer is 70.
[Question]This evening in the nighttime sky over Texas, Mars can be seen until 12:10 AM. Jupiter does not appear until 2 hours and 41 minutes later, and Uranus does not appear until 3 hours and 16 minutes after Jupiter makes its first appearance. How many minutes after 6:00 AM does Uranus first appear in the evening sky over Texas this evening?
[Answer]Jupiter appears 2 hours and 41 minutes after 12:10 AM, which can be calculated in two parts;. 2 hours after 12:10 AM is 12:10 + 2:00 = 2:10 AM. And an additional 41 minutes after 2:10 AM is 2:10 + 0:41 = 2:51 AM. Uranus appears 3 hours and 16 minutes after 2:51 AM, which can be calculated in two parts:. 3 hours after 2:51 AM is 2:51 + 3:00 = 5:51 AM. And 16 minutes after 5:51 AM is 5:51 + 0:16 = 5:67 AM = 6:07 AM. Thus, 6:07 AM is 7 minutes after 6:00 AM. The answer is 7.
Q: Randy got 90, 98, 92, and 94 in his first four quizzes. His goal is to get a 94 average on his 5 quizzes. What score should he get in the fifth quiz to reach his desired average?
A: Since Randy wants to get an average of 94, then the sum of the 5 quizzes should be 94 x 5 = 470. The sum of Randy's score for the first four quizzes is 90 + 98 + 92 + 94 = 374. Thus, Randy needs to get 470 - 374 = 96 in his fifth quiz. The answer is 96.
Question: James buys $3000 worth of stuff from Amazon. He has to return a TV that cost $700 and a bike that cost $500. He also sells another bike that cost 20% more than the bike he returned for 80% of what he bought it for. He then buys a toaster for $100. How much is he out of pocket for everything?
Answer:
The items he returned were valued at $700 + $500 = $1200. So far he is out 3000 - 1200 = 1800 after recouping 1200. An item that is 20% more expensive cost 1 + .2 = 1.2 times as much as the item. So that means the bike he sold cost $500 * 1.2 = $600. He sold it for $600 * .8 = $480. From the bike that he had bought for 600, he was out 600 - 480 = 120. So far he is out 1800 + 120 = 1920. If he also bought a toaster worth 100, he was out 1920 + 100 = 2020. The answer is 2020.
