[Question]Ms. Alice can grade 296 papers in 8 hours. How many papers can she grade in 11 hours?
[Answer]First you must recognize that the problem involves finding the rate of how fast Ms. Alice can grade papers. To find how many papers she can grade in 11 hours, it would be useful to first find out how many papers she can grade in one hour. To do so, divide 296 papers by 8 hours, 296 / 8, to get 37. Therefore, Ms. Alice can grade 37 papers in one hour. To find out how many papers she can grade in 11 hours, multiply the number of papers she can grade in one hour by 11. 37 * 11 gives you 407. Ms. Alice can grade 407 papers in 11 hours. The answer is 407.
Q: Samantha bought a crate of 30 eggs for $5. If she decides to sell each egg for 20 cents, how many eggs will she have left by the time she recovers her capital from the sales?
A: There are 100 cents in each $1 so $5 gives 5 * 100 cents = 500 cents. To recover her capital of 500 cents from a selling price of 20 cents per egg she has to sell 500 / 20 = 25 eggs. There were 30 eggs in the crate to start with so she will have 30 - 25 = 5 eggs left. The answer is 5.

[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.
