Question: Troy had 300 straws. He fed 3/5 of the straws to the adult pigs and an equal number of straws to the piglets. If there were 20 piglets, how many straws did each piglet eat?
Answer with step-by-step thinking: The adult pigs ate 3 / 5 * 300 = 180 straws. The total number of straws that the piglets shared is 300 - 180 = 120. Since there were 20 piglets, each piglet ate 120 / 20 = 6 straws.
So the answer is 6.

Question: Emily wants to know how much it rained last week. She sees that it rained 2 inches on Monday morning and 1 more inch later that day. It rained twice that much on Tuesday. It did not rain on Wednesday but on Thursday it rained 1 inch. The biggest storm was on Friday when the total was equal to Monday through Thursday combined. What was the daily average rain total for the week?
Answer with step-by-step thinking: The total rain was 2 inches + 1 inches = 3 inches on Monday. The total rain was 2 * 3 inches = 6 inches on Tuesday. The total rain was 0 inches + 1 inch = 1 inch across Wednesday and Thursday. The total rain was 3 inches + 6 inches + 1 inch = 10 inches on Friday. There were 3 inches + 6 inches + 1 inch + 10 inches = 20 inches total last week. 20 inches / 5 days = 4 inches average daily rain.
So the answer is 4.

Question: Rita is reading a five-chapter book with 95 pages. Each chapter has three pages more than the previous one. How many pages does the first chapter have?
Answer with step-by-step thinking:
Let P be the number of pages in the first chapter. The second chapter has P + 3 pages. The third chapter has P + 3 + 3 = P + 6 pages. The fourth chapter has P + 6 + 3 = P + 9 pages. The fifth chapter has P + 9 + 3 = P + 12 pages. The whole book has P + 3 + P + 6 + P + 9 + P + 12 = 5P + 30 = 95 pages. Thus, without the 30 extra pages from additional chapters, 5P = 95 - 30 = 65 pages. Therefore, the first chapter had P = 65 / 5 = 13 pages.
So the answer is 13.
