Question: Janet buys 45-pound containers of cat litter for $21 each. If her cat litter box holds 15 pounds of cat litter, and she changes out the litter weekly, how much will it cost, in dollars, for her to buy enough litter to last 210 days?
Answer: If she changes the box weekly, then in 210 days, she will change the box 210 / 7 = 30 times. At 15 pounds of litter for every box change, she will require 30 * 15 = 450 pounds of cat litter in 210 days. If she buys 45 - pound containers, then for 450 pounds she will need to buy 450 / 45 = 10 containers of litter. At $21 per container, to buy enough cat litter for 210 days, it will cost 10 * $21 = $210. The answer is 210.
[Question]After trick-or-treating, Brent dumped his candy on the table. He had received 5 Kit-Kat bars, three times that amount in Hershey kisses, 8 boxes of Nerds, and 11 lollipops. He also had 10 Baby Ruths and half that amount in Reese Peanut butter cups. After giving his little sister 5 lollipops, how many pieces of candy did Brent have left?
[Answer]He had 5 Kit - Kats and had 3 times that amount in Kisses so he had 5 * 3 = 15 Hershey kisses. He had 10 Baby Ruths and half that amount in Reese Peanut butter cups so he had 10 / 2 = 5 Reese Peanut Butter cups. He had 11 lollipops and gave 5 to his sister so he now had 11 - 5 = 6 lollipops. When you add up all of the candy, he had 5 Kit - Kats, 15 Hershey kisses, 10 Baby Ruths, 5 Reese cups, 8 Nerds and 6 lollipops so 5 + 15 + 10 + 5 + 8 + 6 = 49 pieces of candy. The answer is 49.
Q: Tim decides to get animals for his zoo. He buys 3 goats for $400 each. He gets twice as many llamas which cost 50% more each. How much did he spend?
A: The goats cost 3 * 400 = $1200. He buys 3 * 2 = 6 llamas. Each llama cost 400 * 1.5 = $600. So he spends 600 * 6 = $3600 on llamas. So the total cost was 1200 + 3600 = $4800. The answer is 4800.
Question: Julio has four bottles of orange soda and seven bottles of grape soda in his fridge. His friend Mateo has a bottle of orange soda and 3 bottles of grape soda in his fridge. If the amount of beverage in each bottle is 2 liters, how many more liters of soda does Julio have?
Answer: Julio has 4 * 2 = 8 liters of orange soda. Julio also has 7 * 2 = 14 liters of grape soda. Julio therefore has a total of 8 + 14 = 22 liters of soda. The amount of orange soda that Mateo has is 1 * 2 = 2 liters of orange soda. In addition, Mateo has 3 * 2 = 6 liters of grape soda. In total, Mateo has 2 + 6 = 8 liters of soda. This means that Julio has 22 - 8 = 14 liters more of soda. The answer is 14.
[Question]Jason bought a new bookcase that can hold a maximum of 80 pounds of weight. Jason has 70 hardcover books that each weigh half a pound, 30 textbooks that each weigh 2 pounds, and 3 knick-knacks that each weight 6 pounds. How many pounds over the bookcase's weight limit is this total collection of items?
[Answer]First find the total weight of the hardcover books: 70 books * .5 pound / book = 35 pounds. Then find the total weight of the textbooks: 30 books * 2 pounds / book = 60 pounds. Then find the total weight of the knick - knacks: 3 knick - knacks * 6 pounds / knick - knack = 18 pounds. Then find the total weight of all the items: 35 pounds + 60 pounds + 18 pounds = 113 pounds. Then subtract the bookcase's weight limit: 113 pounds - 80 pounds = 33 pounds. The answer is 33.
