[Question]James won a money prize at a charity raffle. He donated half of his winnings back to the charity, then spent $2 on a hot dog to celebrate his win. He had $55 left over. How many dollars did he win?
[Answer]Let W be equal to James’s raffle winnings. He donated half his winnings, so he had W - W / 2 = W / 2 left. He then spent $2 on a hot dog, so W / 2 - 2 = $55. Thus, half his winnings is W / 2 = 55 + 2 = 57. James won W = 57 * 2 = $114. The answer is 114.
Q: For breakfast, Anna bought a bagel for $0.95 and a glass of orange juice for $0.85. At lunch, Anna spent $4.65 on a sandwich and $1.15 on a carton of milk. How much more money did Anna spend on lunch than on breakfast?
A: The total cost of breakfast is $0.95 + $0.85 = $1.80. The total cost of lunch is $4.65 + $1.15 = $5.80. Anna spent $5.80 − $1.80 = $4 more on lunch than breakfast. The answer is 4.
Question: Stella collects stamps. She counted 50 pages in her collector's album. There are 5 rows of 30 stamps in each of the first 10 pages of her album. The rest of the pages each have 50 stamps. How many stamps are in Stella's album?
Answer:
There are 30 x 5 = 150 stamps on each of the first 10 pages. So she has a total of 150 x 10 = 1500 stamps in the first 10 pages. There are 50 - 10 = 40 pages that have 50 stamps each. There is a total of 40 x 50 = 2000 stamps in the remaining 40 pages. Therefore, Stella has 2000 + 1500 = 3500 stamps in her album. The answer is 3500.
