[Question]In one day, Ella's dog eats 4 pounds of food for every one pound of food that Ella eats. How much food do Ella and her dog in 10 days if Ella eat 20 pounds of food each day?
[Answer]If Ella's dog eats 4 pounds of food for every one pound of food that Ella eats, when Ella eats 20 pounds of food in a day, Ella's dog eats 4 * 20 = 80 pounds of food. Together, in one day, Ella and her dog eats 80 + 20 = 100 pounds. In 10 days, Ella and her dog will eat 10 * 100 = 1000 pounds of food. The answer is 1000.

[Question]Brenda is a vet who needs to spay some cats and twice as many dogs. If she needs to spay 21 animals total today, how many cats does she need to spay?
[Answer]Let c be the number of cats Brenda needs to spay and d be the number of dogs. We know that c + d = 21 and d = 2c. Substituting the second equation into the first, we get c + 2c = 21. Combining like terms, we get 3c = 21. Dividing both sides by 3, we get c = 7. The answer is 7.
Q: The price of an iPhone fell 10% in a particular month and another 20% in the second month. If the initial price was $1000, calculate the price after the second month.
A: In the first month, the price of the iPhone fell by 10 / 100 * $1000 = $100. The new price after the first month is $1000 - $100 = $900. In the second month, the price fell 20% further by 20 / 100 * $900 = $180. The new price after the second month is $900 - $180 = $720. The answer is 720.
Question: Christian and Sue wanted to get a $50.00 bottle of perfume for their mom for her birthday. Christian had $5.00 saved up and Sue had $7.00. Christian then mowed 4 of his neighbors' yards, charging $5.00 each, while Sue walked 6 dogs for her neighbors, charging $2.00 per dog. How much more money will Christian and Sue need to make in order to buy the bottle of perfume for their mom?
Answer:
Christian just mowed 4 yards at $5.00 each so he made 4 * 5 = $20.00. Sue just walked 6 dogs at $2.00 each so she made 6 * 2 = $12.00. Christian had $5.00 saved and just made $20.00 while Sue had $7.00 saved and just made $12.00 so together they had 5 + 20 + 7 + 12 = $44. The perfume cost $50.00 and they had $44.00 so they needed to make 50 - 44 = $6.00 more dollars. The answer is 6.
