[Question]Kelly has 8 chickens that lay 3 eggs each per day. If Kelly sells these eggs for $5 a dozen. How much money will she make in 4 weeks if she sells all her eggs?
[Answer]Each chicken lays 7 * 3 = 21 eggs a week. Each week all the chickens lay 21 * 8 = 168 eggs. In 4 weeks all the chickens lay 168 * 4 = 672 eggs. 672 eggs equal 672 / 12 = 56 dozens. Kelly would make 56 * 5 = 280 dollars. The answer is 280.
Q: On a construction site, the Laker cement factory provided 500 bags of cement sold to Mr. Zander at $10 per bag. Mr. Zander also received twenty lorries of construction sand, each carrying 10 tons of sand, sold at $40 per ton. How much money did Mr. Zander pay for these construction materials?
A: The total cost for the sand is 500 * 10 = $5000. Since each lorry was carrying 10 tons of sand, the twenty lorries carried 20 * 10 = 200 tons. At $40 per ton, Mr. Zander paid 200 * $40 = $8000 for the sand that was delivered to his construction site. Altogether, Mr. Zander paid $8000 + $5000 = $13000 for the delivered construction materials. The answer is 13000.
Question: Mary, Edna, and Lucy are athletes who train every Saturday. Mary ran 3/8 of a 24-kilometer field on one Saturday. Edna ran 2/3 of the distance of Edna, and Lucy ran 5/6 of the distance of Edna. How many more kilometers should Lucy run to cover the same distance as Mary?
Answer: Mary ran 3 / 8 x 24 = 9 kilometers. Edna ran 2 / 3 x 9 = 6 kilometers. Lucy ran 5 / 6 x 6 = 5 kilometers. Lucy should run 9 - 5 = 4 kilometers more. The answer is 4.
Q: Maria is chopping up vegetables for a stew. She wants to cut up six times as many carrots as potatoes, twice as many onions as carrots, and 1/3 as many green beans as onions. If she has two potatoes, how many green beans does she need to cut?
A:
First find how many carrots Maria needs to cut by multiplying the number of potatoes by 6: 6 * 2 = 12. Then find how many onions she needs by multiplying the number of carrots by 2: 12 * 2 = 24. Finally, divide the number of onions by 3 to find the number of green beans she needs 24 / 3 = 8. The answer is 8.
