Arthur makes $100 because .05 x 2000 = 100. Arthur can buy 16 comic books because 100 / 6 = 16 and (2 / 3). The comic books cost $96 because 16 x 6 = 96. He has $4 leftover because 100 - 96 = 4.
The answer: 4
Reverse engineering the question: Arthur wants to sell his basketball card collection and use the money to buy comic books. The store owner tells him that each card is worth 5 cents and comic books cost $6 each.

Reasoning and answer: Their novel is half as long as their 300 - page history book so it is 300 / 2 = 150 pages. Their science book has 4 times the amount of pages as their novel, which is 150 pages, so their science book has 4 * 150 = 600 pages.
The answer: 600

If it takes on average 3 minutes to get dressed, then it takes 15 minutes total on the school week because 5 x 3 = 15. Thus far this week it has taken him 13 minutes to get dressed because 2 + 4 + 3 + 4 = 13. To tie his previous method, he needs to take 2 minutes on Friday because 15 - 13 = 2.
The answer: 2
Reverse engineering the question: Osborn is testing a new way to get dressed in the morning on school days so he goes faster and can get up later. He tracks his time for the week and on Monday is takes him 2 minutes. On Tuesday it takes him 4 minutes. On Wednesday it takes him 3 minutes. On Thursday it takes him 4 minutes. Before Friday arrives he looks at his old way of getting dressed and sees that it was taking him 3 minutes on average to get dressed. How fast does he have to get dressed on Friday so his weekly average ties his old method?


Reasoning and answer: First find the total number of games Bill has won: 200 games * 63% = 126 games. Then find how many of the next 100 games he wins by subtracting the number he loses from the total: 100 games - 43 games = 57 games. Then add his new wins to his old wins to find his total wins: 57 games + 126 games = 183 games. Then add the old total number of games to the new total number of games to find the overall total number of games: 200 games + 100 games = 300 games. Then divide the total number of games Bill won by the overall total number of games and multiply by 100% to find the percentage of games he won: 183 games / 300 games * 100% = 61%.
The answer: 61

She buys a $4.00 latte in the morning for 5 days so that’s 4 * 5 = $20.00. She buys a $2.00 iced coffee 3 days a week so that’s 2 * 3 = $6.00. In one week she spends $20.00 on lattes and $6.00 on iced coffee for a total of 20 + 6 = $26.00. After 1 year, 52 weeks, she spends 52 * 26 = $1,352.00. She wants to cut her coffee spending by 25% so that will save her .25 * 1352 = $338.00.
The answer: 338
Reverse engineering the question: Martha buys 1 latte for $4.00 every morning, 5 days a week. 3 days a week, she buys an iced coffee for $2.00. Her goal for the entire year is to cut her coffee spending by 25%. How much will she save?


In total, the 3 tea leaf plants have 18 x 3 = 54 green leaves. One - third of the yellow leaves falling off of all plants is 54 / 3 = 18. The number of remaining green leaves on the plants is 54 - 18 = 36.
The answer: 36
Reverse engineering the question:
There are 18 green leaves on each of the 3 tea leaf plants. One-third of them turn yellow and fall off on each of the tea leaf plants. How many green leaves are left on the tea leaf plants?
