The 40 - ounce container can hold 40 / 8 = 5 cups of water. This means that 5 * 3 = 15 tablespoons of soap should be used, since each cup of water requires 3 tablespoons of soap.
The answer: 15
Reverse engineering the question: A mother is making her own bubble mix out of dish soap and water for her two-year-old son. The recipe she is following calls for 3 tablespoons of soap for every 1 cup of water. If the container she hopes to store the bubble mix in can hold 40 ounces of liquid, and there are 8 ounces in a cup of water, how many tablespoons of soap should she add to the container (assuming that the soap itself doesn't count towards the capacity of the container)?


Reasoning and answer: Robin ate twice as many buttercream cupcakes as chocolate sauce cupcakes, or 2 * 4 = 8. So in total she ate 4 + 8 = 12 cupcakes.
The answer: 12

Question: Robin likes to bake cupcakes for friends and to make her puppy North happy. Once Robin ate four cupcakes with chocolate sauce and twice as many cupcakes with buttercream frosting on her own. How many cupcakes did Robin eat?


There are 7 days in a week, so if he doesn't go to work for 3 days, he goes 7 - 3 = 4 days every week. He travels 140km each day for a weekly total of 140 * 4 = 560km. In 4 weeks he will travel a total of 4 * 560 = 2240km.
The answer: 2240
Reverse engineering the question: Francine drives 140km to work each day. If she does not go to work 3 days every week, find the total distance she drives to work for 4 weeks in kilometers.


Reasoning and answer: First find the total number of milliliters in the bottle: 2 liters * 1000 ml / liter = 2000 ml. Then divide the total number of milliliters by the amount she drinks per sip: 2000 ml / 40 ml = 50 sips. Then multiply the number of sips by the time per sip to find the time it takes her to drink the bottle: 50 sips * 5 minutes / sip = 250 minutes.
The answer: 250

Question: Marcy keeps a 2-liter bottle of water by her desk. She takes a sip every five minutes, and each sip is 40 ml. How many minutes does it take her to drink the whole bottle of water?


There are a total of 1000 spaces - 320 spaces = 680 spaces in both sections 2 and 3. Let the number of spaces in section 3 be x. The number of spaces in section 2 = x + 200. We know that 320 + x + 200 + x = 1000. Combining like terms, we get 2x = 480. Dividing both sides by 2 produces x = 240. The number of spaces in section 2 is 240 + 200 = 440.
The answer: 440
Reverse engineering the question: A 1000 car parking lot is divided into 3 sections. There are 320 spaces in section 1, and 200 more in section 2 than in section 3. How many spaces are made available in section 2 of the parking lot?


7 leaves fell in the first hour. 4 leaves fell in the second hour. 4 leaves fell in the third hour. The total number of leaves that fell during the 3 hours is 7 + 4 + 4 = 15 leaves. The average number of leaves that fell per hour is 15 leaves / 3 hours = 5 leaves per hour.
The answer: 5
Reverse engineering the question:
Rylee is bored and decides to count the number of leaves falling off the tree in her backyard. 7 leaves fall in the first hour. For the second and third hour, the leaves fall at a rate of 4 per hour. What is the average number of leaves which fell per hour?
