Question: Janet lives in a city built on a grid system. She walks 3 blocks north, then seven times as many blocks west. Then she turns around and walks 8 blocks south and twice as many blocks east in the direction of her home. If Janet can walk 2 blocks/minute, how long will it take her to get home?
Answer: First, find the total number of blocks south Janet is from her starting point by subtracting the blocks she walked north from the blocks she walked south: 8 blocks - 3 blocks = 5 blocks. Then find the number blocks she walked west: 3 blocks * 7 = 21 blocks. Then find the number of blocks she walked east: 8 blocks * 2 = 16 blocks. Subtract the number of blocks she walked east from the number of blocks she walked west to find how many blocks west of her starting point she is: 21 blocks - 16 blocks = 5 blocks. Add the number of blocks she needs to walk north to the number of blocks she needs to walk east: 5 blocks + 5 blocks = 10 blocks. Finally, divide the distance she needs to walk by her speed to find how long she'll spend walking: 10 blocks / 2 blocks / minute = 5 minutes. The answer is 5.
[Question]In January the families visiting a national park see animals 26 times. In February the families that visit the national park see animals three times as many as were seen there in January. Then in March the animals are shyer and the families who visit the national park see animals half as many times as they were seen in February. How many times total did families see an animal in the first three months of the year?
[Answer]Animals were seen 26 times in January and three times as much in February, 26 x 3 = 78 times animals were seen in February. In March the animals were seen 1 / 2 as many times as were seen in February, 78 / 2 = 39 times animals were seen in March. If animals were seen 26 times in January + 78 times in February + 39 times in March = 143 times animals were seen in the first three months of the year. The answer is 143.
Q: Maryann spends seven times as long doing accounting as calling clients. If she worked 560 minutes today, how many minutes did she spend calling clients?
A: Let a be the amount of time Maryann spends doing accounting and c be the amount of time she spends calling clients: We know that a + c = 560 and a = 7c. Substituting the second equation into the first equation, we get 7c + c = 560. Combining like terms, we get 8c = 560. Dividing both sides by 8, we get c = 70. The answer is 70.
Question: Leila and her friends want to rent a car for their one-day trip that is 150 kilometers long each way. The first option for a car rental costs $50 a day, excluding gasoline. The second option costs $90 a day including gasoline. A liter of gasoline can cover 15 kilometers and costs $0.90 per liter. Their car rental will need to carry them to and from their destination. How much will they save if they will choose the first option rather than the second one?
Answer: Leila and her friends will travel a total distance of 150 x 2 = 300 kilometers back - and - forth. They will need 300 / 15 = 20 liters of gasoline for this trip. So, they will pay $0.90 x 20 = $18 for the gasoline. Thus, the first option will costs them $50 + $18 = $68. Therefore, they can save $90 - $68 = $22 if they choose the first option. The answer is 22.
[Question]Tim's website got 100 visitors a day for the first 6 days and then on the last day of the week it got twice as many visitors as every other day combined. If he gets $.01 per visit how much did he make that week?
[Answer]In the first 6 days, he got 6 * 100 = 600 visits. So on the 7th day, he got 600 * 2 = 1200 visitors. So he got a total of 1200 + 600 = 1800 visitors. That means he made 1800 * .01 = $18. The answer is 18.
[Question]Annie is a mother of 3 children: Mark, Matt, and Mike. She decided to give them some fruits. Mike received 3 oranges. Matt got twice as many apples, and Mark got as many bananas as Mike and Matt received fruits altogether. How many fruits do the three children have in total?
[Answer]
Mike received 3 oranges. Matt received twice as many apples as Mike received oranges, so he got 3 * 2 = 6 apples. Mark received 6 + 3 = 9 bananas. So in total, all children received 3 + 6 + 9 = 18 fruits. The answer is 18.
