Question: At Mrs. Dawson's rose garden, there are 10 rows of roses. In each row, there are 20 roses where 1/2 of these roses are red, 3/5 of the remaining are white and the rest are pink. How many roses at Mrs. Dawson's rose garden are pink?
Answer: There are 20 x 1 / 2 = 10 red roses in each row. So there are 20 - 10 = 10 roses that are not red in each row. Out of the 10 remaining roses in each row, 10 x 3 / 5 = 6 roses are white. Thus, there are 10 - 6 = 4 pink roses in each row. Therefore, Mrs. Dawson has 4 pink roses each in 10 rows for a total of 4 x 10 = 40 pink roses in her rose garden. The answer is 40.

Q: A bag was originally priced at $500. A week after, the price was reduced by 5%. Since the bag was still not sold, the selling price was reduced by 4% a month after. How much was the total reduction from the original selling price?
A: The original price of the bag was reduced by $500 x 5 / 100 = $25. So its selling price after a week was $500 - $25 = $475. The price of the bag was again reduced by $475 x 4 / 100 = $19. So, its selling price now is $475 - $19 = $456. Therefore, the total reduction from the selling price is $500 - $456 = $44. The answer is 44.
Question: Unrest leads to 30 days of protest in 21 different cities. In each city, there are 10 arrests per day. The average person spends 4 days in jail before trial and then spends half of a 2-week sentence. How many combined weeks of jail time are there?
Answer: Each city arrest 30 * 10 = 300 people during the protest. So a total of 300 * 21 = 6300 people were arrested. They spend 14 / 2 = 7 days of their sentence in jail. So they spend a total of 7 + 4 = 11 days in jail. So there was a total of 6300 * 11 = 69300 days in jail. So they spent 69300 / 7 = 9900 weeks in jail. The answer is 9900.
[Question]Jane sews 2 dresses a day for 7 days. Then she sews 3 dresses a day for the next 2 days. In the end, she adds 2 ribbons to each dress. How many ribbons does Jane use in total?

The total number of hours each worker works in the first 2 days is 10 + 8 = 18 hours. Since they completed the job in three days, each was compensated for 18 + 15 = 33 hours of work. Mr Fletcher paid each of the workers $10 per hour of work, meaning for 33 hours, each of the workers received 33 * $10 = $330. Since they were two workers, the total amount they received all together after each was paid $330 is $330 * 2 = $660. The answer is 660.
