[Question]Alan has 8 pine trees in his backyard and each tree drops 200 pine cones. If 30% of the pine cones fall on Alan's roof, and each pine cone weighs 4 ounces, how many ounces of pine cones does Alan have on his roof?
[Answer]First find the total number of pine cones: 8 trees * 200 pine cones / tree = 1600 pine cones. Then multiply that number by 30% to find how many fall on Alan's roof: 1600 pine cones * 30% = 480 pine cones. Then multiply that number by the weight of each pine cone to find the total weight of the pine cones: 480 pine cones * 4 ounces / pine cone = 1920 ounces. The answer is 1920.

Question: Mr. Banks and Ms. Elizabeth are entrepreneurs who invest in different income streams and earn revenue from the investments. From each of his eight investments, Mr. Banks received $500 in revenue. Ms. Elizabeth also received $900 from each of her 5 investment streams.

[Question]Clara is selling boxes of cookies to raise money for a school trip. There are 3 different types for sale. The first type has 12 cookies per box. The second type has 20 cookies per box, and the third type has 16 cookies per box. If Clara sells 50 boxes of the first type, 80 boxes of the second type, and 70 boxes of the third type, how many cookies does she sell?
[Answer]Clara sells 600 cookies of the first type because 12 * 50 = 600. She sells 1600 cookies of the second type because 20 * 80 = 1600. She sells 1120 cookies of the third type because 16 * 70 = 1120. Thus, Clara sells 3300 cookies total because 600 + 1600 + 1120 = 3320 cookies. The answer is 3320.
