Question: A book is 98 pages long. Half of the pages are filled with images, and 11 with an introduction. Of the remaining pages, half are blank and the other half are filled with text. How many pages with text are there?
Answer: Half of the pages are images, which means 98 * 0.5 = 49 pages. So there are 98 - 49 - 11 pages for the introduction = 38 remaining pages. Half of the remaining pages are filled with text, which means 38 * 0.5 = 19 pages. The answer is 19.

Question: Iris has a berry farm. Her brother and sister help her to pick up the berries and sell them to the market. Iris picked 30 blueberries, her sister picked 20 cranberries, and her brother was able to pick 10 raspberries. If 1/3 of the total berries they were able to pick are rotten and the remaining 1/2 of the fresh berries need to be kept, how many berries will they be able to sell?
Answer: Iris and his brother and sister were able to pick a total of 30 + 20 + 10 = 60 berries. The rotten berries that needed to be thrown away are (1 / 3) x 60 = 20. So, the total number of fresh berries is 60 - 20 = 40. The berries they need to keep are (1 / 2) x 40 = 20. Therefore, the total number of berries they will be able to sell is 40 - 20 = 20. The answer is 20.
