Question: Amy bakes muffins for her friends. On Monday, she brings 1 muffin to school to share. Each day for the rest of the week she brings one more muffin to school than she did the day before. If on Saturday she counts that there are 7 muffins left, how many did she originally bake?
Answer: On Tuesday, she brings in 1 + 1 = 2 muffins. On Wednesday, she brings in 2 + 1 = 3 muffins. On Thursday, she brings in 3 + 1 = 4 muffins. On Friday, she brings in 4 + 1 = 5 muffins. In total, she brought 1 + 2 + 3 + 4 + 5 = 15 muffins to school to share with her friends. She baked a total of 15 + 7 = 22 muffins. The answer is 22.
[Question]Georgina owns a parrot and is teaching it to speak. So far, the parrot knows seventeen phrases. If she is teaching it two phrases a week and it already knew three phrases when she bought it, how many days has Georgina had it?
[Answer]The parrot knew 3 phrases when Georgina bought it, so it has learned 17 - 3 = 14 phrases from her. She has been teaching it 2 phrases a week, so she has had it 14 / 2 = 7 weeks. There are 7 days in a week, so Georgina has had the parrot for 7 * 7 = 49 days. The answer is 49.
Q: A father is building a playset for his son and needs to purchase lumber, nails, and fabric. When he started planning the project, the necessary lumber cost $450, the nails cost $30, and the fabric cost $80. However, recent economic inflation has caused the price of lumber to increase by 20%, the price of nails to increase by 10%, and the price of fabric to increase by 5%. In dollars, how much more money will it cost to complete the project now (after inflation) than it would have when the father began planning?
A: First, the initial, pre - inflation, cost of the project was 450 + 30 + 80 = $560. Then, the price of the lumber increased to 450 * 1.20 = $540. Similarly, the price of the nails increased to 30 * 1.10 = $33. And the price of the fabric increased to 80 * 1.05 = $84. Therefore, the new, post - inflation, cost of the project is 540 + 33 + 84 = $657. Thus, the cost has increased by 657 - 560 = $97. The answer is 97.
Question: Jane plans on reading a novel she borrows from her friend. She reads twice a day, once in the morning and once in the evening. In the morning she reads 5 pages and in the evening she reads 10 pages. If she reads at this rate for a week, how many pages will she read?
Answer:
The number of pages Jane reads in a day is 5 in the morning and 10 in the evening, so she reads 10 + 5 = 15 pages in a day. If she reads for a week she reads for 7 days, so by the end of the week she reads 15 * 7 = 105 pages. The answer is 105.
