[Question]Phillip wants to make pickles with the supplies he finds at home. He has 4 jars, 10 cucumbers, and 100 oz of vinegar. Each cucumber makes six pickles. Each jar can hold 12 pickles. It takes 10 ounces of vinegar per jar of pickles. When he is all done making as many pickles as he has supplies for, how many ounces of vinegar are left?
[Answer]The jars allow him to make 48 pickles because 4 x 12 = 48. The cucumbers allow him to make 60 pickles because 10 x 6 = 60. The vinegar allows him to make 10 jars of pickles because 100 / 10 = 10. The vinegar is enough to make 60 pickles because 10 x 6 = 60. He can make 48 pickles because 48 < 60. He needs 4 jars to make this because 48 / 12 = 4. He needs 40 ounces of vinegar because 4 x 10 = 40. He has 60 ounces remaining because 100 - 40 = 60. The answer is 60.
Q: A squirrel had stashed 210 acorns to last him the three winter months. It divided the pile into thirds, one for each month, and then took some from each third, leaving 60 acorns for each winter month. The squirrel combined the ones it took to eat in the first cold month of spring before plants were in bloom again. How many acorns does the squirrel have to eat at the beginning of spring?
A: The squirrel split the 210 acorns into thirds, so it had 3 piles of 210 / 3 = 70 acorns. It took 70 - 60 = 10 from each pile. The squirrel will have 3 * 10 = 30 acorns to eat at the beginning of spring. The answer is 30.
Question: Mark has an egg farm. His farm supplies one store with 5 dozen eggs and another store with 30 eggs each day. How many eggs does he supply these two stores in a week?
Answer: Since a dozen is equal to 12, then Mark's egg farm supplies one store with 5 x 12 = 60 eggs each day. It supplies the two stores with a total of 60 + 30 = 90 eggs each day. Therefore, the egg farm supplies the two stores with 90 x 7 = 630 eggs in a week. The answer is 630.
[Question]Mr. Llesis had 50 kilograms of rice. He kept 7/10 of it in storage and gave the rest to Mr. Everest. How many kilograms of rice did Mr. Llesis keep than Mr. Everest?
[Answer]Mr. Llesis kept 50 x 7 / 10 = 35 kilograms of rice. So, he gave 50 - 35 = 15 kilograms of rice to Mr. Everest. Therefore, Mr. Llesis kept 35 - 15 = 20 kilograms more than Mr. Everest. The answer is 20.
[Question]Wendi brought home 4 chickens. After a few days, she brought home enough additional chickens to double the number of chickens she owned. Then, a neighbor's dog ate one of her chickens. Finally, Wendi found an additional 4 less than ten chickens and brought them home too. After this, how many chickens does Wendi have?
[Answer]
Wendi doubled her number of chickens from 4 to 4 * 2 = 8 chickens. After a dog ate one of the chickens, 8 - 1 = 7 chickens remained. 4 less than 10 is 10 - 4 = 6. Therefore, Wendi added another 4 less than ten chickens for a total of 7 + 6 = 13 chickens. The answer is 13.
