Question: There are 4 more Muscovy ducks than Cayugas, and 3 more than twice as many Cayugas as Khaki Campbells. If there are 90 ducks total, how many Muscovies are there?
Answer: Let x represent the number of Khaki Campbell ducks. Cayugas:3 + 2x. Muscovies:4 + (3 + 2x) = 7 + 2x. Total: x + 3 + 2x + 7 + 2x = 90. 5x + 10 = 90. 5x = 80. x = 16. Muscovy: 7 + 2(16) = 39. The answer is 39.

[Question]Mary and her two friends agreed to evenly pay for the cost of 2 pounds of chicken. Mary's mother went to the grocery and bought the 2-pound chicken, 3 pounds of beef that cost $4 per pound, and a liter of oil that costs $1. If Mary's mother paid a total of $16 for the grocery, how much should Mary and her two friends pay each for the chicken?
[Answer]Three pounds of beef cost $4 x 3 = $12. Mary's mother paid $12 + $1 = $13 for the beef and oil. Hence, the 2 - pound chicken cost $16 - $13 = $3. There are 1 (Mary) + 2 friends = 3 people who will split the $3 cost. Therefore, each of them will pay $3 / 3 = $1. The answer is 1.
[Question]Miles and Daphne are comparing their reading collection and want to figure out who has more pages. They are about to count each page, but their parents suggest that they see whose collection is taller. Mile's collection is taller, but then Daphne notices that Miles reads board books, and so the pages are thicker. After some more measuring, they figure out that for Miles, 1 inch equals 5 pages, but for Daphne 1 inch equals 50 pages. If Miles's books are 240 inches tall and Daphne's collection is 25 inches tall, how many pages are in the longest collection?
[Answer]
Miles's collection has 1,200 pages because 240 x 5 = 1,200. Daphne's collection has 1,250 pages because 25 x 50 = 1,250. The largest collection has 1,250 pages because 1,250 > 1,200. The answer is 1250.
