Step-by-step reasoning process: Luke started putting together, 1000 x 0.1 = 100 pieces. The next day, there were 1000 - 100 = 900 pieces left. Then he put together 900 * 0.2 = 180 pieces on the second day. So there were 900 - 180 = 720 pieces left. On the third day, he put together 720 * 0.3 = 216 pieces. Therefore, Luke still has 720 - 216 = 504 pieces left to complete the puzzle.
[Q & A] The question is Luke started working on a 1000-piece jigsaw puzzle. The first day he worked on it, he put together 10% of the pieces. On the second day, he put together another 20% of the remaining pieces from the first day. On the third day, he put together 30% of the remaining pieces from the previous day. How many pieces does he have left to complete after the third day?
The answer is 504

Step-by-step reasoning process: She averaged 23 points per game because 345 / 15 = 23. She averaged 10 points a game off two - point baskets because 5 x 2 = 10. She averaged 4 points a game from free throws because 4 x 1 = 4. She averaged 14 points a game off non - three point baskets because 10 + 4 = 14. She averaged 9 points from three - pointers because 23 - 14 = 9. She averaged 3 three - pointers a game because 9 / 3 = 3.
[Q & A]
