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. If Arthur sells all 2,000 cards of his and buys as many comic books as he can, how much money does he have leftover?
Answer: 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 is 4.
[Question]The novel that everyone is reading for English class has half as many pages as their history book. Their science book has 4 times the amount of pages as their novel. If the history book has 300 pages, how many pages does their science book have?

Q: 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?
A: 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 is 2.
Question: Bill has played 200 games of poker and won 63% of them. If he plays 100 more games and loses 43 of them, what is his new win percentage?
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 is 61.
[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?
[Answer]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 is 338.
