Reasoning and answer: Mary fed Luna 1 + 1 = 2 cups of kibble. Frank fed Luna 1 - cup plus twice 1 - cup, or 1 + 2 = 3 cups of kibble. In total, they fed Luna 2 + 3 = 5 cups of kibble. Thus, if the new bag held 12 cups of kibble, the next morning, 12 - 5 = 7 cups of kibble remained in the bag.
The answer: 7

Question: Luna, the poodle, is supposed to eat 2 cups of kibble every day. But Luna's master, Mary, and her husband, Frank, sometimes feed Luna too much kibble. One day, starting with a new, 12-cup bag of kibble, Mary gave Luna 1 cup of kibble in the morning and 1 cup of kibble in the evening, But on the same day, Frank also gave Luna 1 cup of kibble in the afternoon and twice as much in the late evening as he had given Luna in the afternoon. The next morning, how many cups of kibble will Mary find remaining in the bag?
Two fifths of $500 is (2 / 5) * $500 = $200. She needed $200 more than $500 which is $200 + $500 = $700. 15% of $700 is (15 / 100) * $700 = $105. She was given a $105 discount so she has to pay $700 - $105 = $595. She would still need $595 - $500 = $95.
The answer: 95
Reverse engineering the question: Mrs. Smith wanted to buy wears worth $500. She went to a boutique with the $500 but by the time she had picked out everything she liked, she realized that she would need two-fifths more money than she had. If the shop owner gave her a discount of 15%, how much more money will she still need?
Reasoning and answer: Jake has 5000 - 2800 = $2200 left. Jake has 2200 / 2 = $1100. Jake loses 1100 / 4 = $275. Jake has 1100 - 275 = $825 left.
The answer: 825

She uses 3 ounces of beans per day because 2 x 1.5 = 3. She uses 21 ounces of beans per week because 7 x 3 = 21. She buys 2 bags of beans per week because 21 / 10.5 = 2. She spends $16 on the beans per week because 2 x 8 = 16. She spends $2 on the milk per week because 4 x (1 / 2) = 2. She spends $18 per week on her coffee because 16 + 2 = 18.
The answer: 18
Reverse engineering the question: Maddie wants to see how much her mom spends on coffee each week. She makes herself 2 cups of coffee per day. Each cup has 1.5 ounces of coffee beans. A bag of coffee costs $8 and contains 10.5 ounces of beans. She uses 1/2 a gallon of milk per week. A gallon of milk costs $4. She doesn't add any sugar to the coffee. How much does she spend on her coffee per week?
Reasoning and answer: The children watch a total of 45 x 4 = 180 minutes in a week. In hours, this is equal to 180 / 60 = 3 hours a week. Thus, these children watch 3 x 2 = 6 hours in two weeks.
The answer: 6

Reasoning and answer: The combined length of all the rope is 41 feet because 8 + 20 + (2 x 3) + 7 = 41. He loses 6 feet from the knots because 5 x 1.2 = 6. The final length is 35 feet because 41 - 6 = 35.
The answer: 35

Question:
Tony wants to build the longest rope he possibly can, so he collects all the rope in his home. He finds an 8-foot rope, a 20-foot rope, three 2 foot ropes, and a 7-foot rope. each knot between the ropes makes him lose 1.2 foot per knot. How long is his rope when he's done tying them all together?
