First, we need to determine how many siblings Billy has. To do this, we perform 2 * 2 = 4 brothers, as he has 2 sisters and twice as many brothers as sisters. Then we divide the total number of sodas in the 12 pack, which is 12, by the number of siblings, performing 12 / 6 = 2 cans per person.
The answer: 2
Reverse engineering the question: Billy buys a 12 pack of soda from the store. If he has twice as many brothers as sisters, and he has 2 sisters, how many sodas can he give to each of his siblings if he wants to give out the entire 12 pack while giving each the same number?
Reasoning and answer: Two sets of metal beads cost 2 x $10 = $20. Therefore, Nancy spends $9 + $20 = $29 in all.

Celia has budgeted $100 a week for 4 weeks for food, $100 x 4 = $400 worth of food for the month. She has one monthly cost of $1500 for her rent + $30 for video streaming services + $50 for her cell phone = $1580 of single monthly costs. Celia wants to set aside 10% of the $400 + $1580 = $1980 for her savings account. 10% of her savings account is .10 x 1980 = $198 to add to her savings account.
The answer: 198
Reverse engineering the question: Celia is creating a budget for the next 4 weeks. She wants to spend no more than $100 a week on food. For rent for her apartment, she plans to spend $1500. She has $30 set aside for video streaming services for the month. She also has $50 planned for one month of cell phone usage. After she adds up all of her spending for the month she wants to set aside 10% of it to put into savings. How much money is Celia going to put into her savings account?
Reasoning and answer: In the first week, each day they pack 40 * 50 = 2000 apples. The total number of apples packed in the boxes is 2000 * 7 = 14000 apples in the first week. When 500 fewer apples were packed each day in the next week, the total became 2000 - 500 = 1500 apples per day. The total number of apples packed in the boxes that week is 1500 * 7 = 10500 apples. The total is 14000 + 10500 = 24500 apples for the two weeks.
The answer: 24500

Question: Malcolm works in a company where they normally pack 40 apples in a box, producing 50 full boxes per day. Operations went as normal in one week. But in the next week, they packed 500 fewer apples per day. What's the total number of apples packed in the two weeks?
First find the number of cheaper coats Karen will have to purchase over 30 years: 30 years / 5 years / coat = 6 coats. Then multiply that number by the cost of one cheaper coat to find the total cost of that option: 6 coats * $120 / coat = $720. Then find the number of more expensive coats Karen will have to purchase over 30 years: 30 years / 15 years / coat = 2 coats. Then multiply that number by the cost of one expensive coat to find the total cost of that option: 2 coats * $300 / coat = $600. Then subtract the total cost of the more expensive coats from the total cost of the less expensive coats to find the difference: $720 - $600 = $120.
The answer: 120
Reverse engineering the question: Karen is considering her winter coat options. One coast costs $300 and will last for 15 years. The other coat costs $120 and will last for five years. How much money would Karen save over 30 years by buying the more expensive cost?
You first need to know the total weight of the vegetables, so you add each quantity: 15 + 13 + 8 = 36 kg. Then you have to find half of 36: 36 / 2 = 18 kg. So, he sold 18 kg of vegetables.
The answer: 18
Reverse engineering the question:
A fruit and vegetable merchant installed 15 kg of carrots, 13 kg of zucchini and 8 kg of broccoli. He sold only half of them. What mass of vegetables did he sell?
