Q: While reading about the history of different towns, Jared learned that Euston had 20 more carriages than Norfolk. Norwich had 100 carriages, and Flying Scotsman had 20 more carriages than Norwich. If Euston had 130 carriages, how many carriages are there in all?
A: If Flying Scotsman had 20 more carriages than Norwich, and Norwich had 100 carriages, then Flying Scotsman had 100 + 20 = 120 carriages. Together, Flying Scotsman and Norwich had 120 + 100 = 220 carriages. If Euston had 130 carriages, 20 more carriages than Norfolk, Norfolk had 130 - 20 = 110 carriages. Together, Euston and Norfolk had 110 + 130 = 240 carriages. Altogether, Euston, Norfolk, Norwich, and Flying Scotsman had 240 + 220 = 460 carriages. The answer is 460.
Question: After geometry class, Bill wants to count how many lines he drew. For each shape, he drew one line per side. If he drew 12 triangles, 8 squares, and 4 pentagons, how many lines did he draw?
Answer: For the triangles, he drew 36 lines because 12 times 3 equals 36. For the squares, he drew 32 lines because 8 times 4 equals 32. For the pentagons, he drew 20 lines because 4 times 5 equals 20. He drew 88 lines in total because 36 plus 32 plus 20 equals 88. The answer is 88.
[Question]Steven's teacher sends the class an assignment to collect 60 different fruit seeds. Apples average 6 seeds, pears average 2 seeds, and grapes average 3 seeds. Steven has set aside 4 apples, 3 pears, and 9 grapes to extract their seeds. How many more seeds does he need to fulfill his assignment?
[Answer]With 4 apples, Steven will collect 4 apples * 6 seeds / apple = 24 seeds. With 3 pears, Steven will collect 3 pears * 2 seeds / pear = 6 seeds. With 9 grapes, Steven will collect 9 grapes * 3 seeds / grape = 27 seeds. In total, Steven will collect 24 seeds + 6 seeds + 27 seeds = 57 seeds. To collect 60 seeds he needs 60 seeds - 57 seeds = 3 more seeds. The answer is 3.
Q: Alex is working on a science project and has taken pictures of all of the plants in a park near her home. She wants to find out how many of each plant she has pictures of, but she has 960 pictures, and counting them all will take her a long time. Her teacher suggested she use a program on the computer that can automatically tell her what plant is in each picture and count them for her. It will take the program 2 minutes to process each picture. How many hours will it take to process all of the pictures?
A: Each picture will take 2 minutes to process. 2 x 960 = 1,920 minutes. There are 60 minutes in an hour. To find the hours, divide the minutes by 60. 1,920 / 60 = 32 hours. The answer is 32.
Question: Cid owns a mechanic shop, he charges $20 for an oil change, $30 for a repair, and $5 for a car wash. How much money did he earn if he changed the oil of 5 cars, repaired 10 cars, and washed 15 cars?
Answer: The money he earned from an oil change is $20 x 5 = $ 100. The money he earned from the repair is $30 x 10 = $300. The money he earned from the car wash is $15 x 5 = $75. Therefore, Cid earned a total of $100 + $300 + $75 = $475. The answer is 475.
Q: Jack is trying to stack cans in his emergency bunker. If he can fit 12 cans in one row, 4 rows on one shelf, and 10 shelves in one closet, how many cans can he store in each closet?
