Question: Lily has 5 lottery tickets to sell. She sells the first ticket for $1. She then sells each successive ticket for a dollar more than the previous ticket. She plans to keep a $4 profit and give the remaining money as the prize. How much money will the winner of the lottery receive?
Answer: The second ticket sold will cost $1 + $1 = $2. The third ticket sold will cost $2 + $1 = $3. The fourth ticket sold will cost $3 + $1 = $4. The fifth ticket sold will cost $4 + $1 = $5. The total money collected is $1 + $2 + $3 + $4 + $5 = $15. After taking profit, the total prize money will be $15 - $4 = $11. The answer is 11.
[Question]There are six chairs in each row in a church. If there are 20 rows of chairs in the church, and each chair holds five people, calculate the number of people who have to sit in the chairs for the church to be full.
[Answer]If there are six chairs in each row in the church, the total number of chairs in the church is 6 * 20 = 120. Since each chair holds 5 people, 5 * 120 = 600 people must sit in all of the chairs for the church to be full. The answer is 600.
Q: Betty is planning to host her friends over for a party. She buys drinks, cakes, and ice creams at a unit cost of $2, $10, and $5 respectively. How much does she spend if she buys 10 drinks, 5 cakes, and 100 ice creams?
A: The amount she spends on buying drinks is $2 * 10 = $20. The amount she spends on buying cakes is $10 * 5 = $50. The amount she spends on buying ice creams is $5 * 100 = $500. The total amount she spends is $20 + $50 + $500 = $570. The answer is 570.
Question: Roger rode his bike for 2 miles this morning, and then 5 times that amount in the evening. How many miles did Roger ride his bike for?
Answer: Roger rode for 2 miles in the morning, and then 5 times that in the evening for 5 * 2 = 10 miles ridden in the evening. In total, that means Roger rode 2 + 10 = 12 miles over the course of the day. The answer is 12.
[Question]James has an old printer that crumples every seventh page and blurs the ink on every third page. If he prints 42 pages, how many are neither crumpled or blurred?
[Answer]First find the total number of pages that are crumpled: 42 pages / 7 = 6 pages. Then find the total number of pages that are blurred: 42 pages / 3 = 14 pages. Then find the number of pages that are both blurred and crumpled by finding how many numbers are less or equal to 42 and divisible by both 3 and 7: there are two, 21 and 42. Then subtract the number of crumpled and blurred pages from the total number of pages, and add the number of pages that were double - counted because they were both blurred and crumpled: 42 pages - 6 pages - 14 pages + 2 pages = 24 pages. The answer is 24.
[Question]Sam and Jeff had a skipping competition at recess. The competition was split into four rounds. Sam completed 1 more skip than Jeff in the first round. Jeff skipped 3 fewer times than Sam in the second round. Jeff skipped 4 more times than Sam in the third round. Jeff got tired and only completed half the number of skips as Sam in the last round. If Sam skipped 16 times in each round, what is the average number of skips per round completed by Jeff?
[Answer]
In round one, Jeff completed 16 - 1 = 15. In round two, Jeff completed 16 - 3 = 13. In round three, Jeff completed 16 + 4 = 20. In round four, Jeff completed 16 / 2 = 8. Jeff completed 15 + 13 + 20 + 8 = 56 skips in total. Jeff skipped an average of 56 / 4 = 14 skips per round. The answer is 14.
