The weight of 12 crates of vegetables is 12 * 4 = 48 kilograms. The weight of 16 cartons of vegetables is 16 * 3 = 48 kilograms. So the total weight of all crates and cartons is 48 + 48 = 96 kilograms.
The answer: 96
Reverse engineering the question: A store transports fresh vegetables in crates and cartons using its delivery truck. One crate of vegetables weighs 4 kilograms and one carton 3 kilograms. How much will a load of 12 crates, and 16 cartons of vegetables weigh?


Reasoning and answer: Jennifer has a total of 212 + 310 + 502 = 1,024 sweets. Jennifer and her friends will get 1,024 / 4 = 256 sweets each.

First find the amount of tape each 15 in x 30 in box needs on the short sides: 2 sides * 15 inches / side = 30 inches. Then add that to the amount of tape each 15 in x 30 in box needs on the long side to find the total amount needed per box: 30 inches + 30 inches = 60 inches. Then multiply that amount by 5 boxes to find the total amount needed: 60 inches / box * 5 boxes = 300 inches. Then find the amount of tape each 40 in x 40 in box needs for its three equal length sides: 3 sides * 40 inches / side = 120 inches. Then multiply that amount by 2 boxes to find the total amount needed: 120 inches / box * 2 boxes = 240 inches. Then add the total amount needed for each box size to find the grand total: 240 inches + 300 inches = 540 inches.
The answer: 540
Reverse engineering the question: Brian is taping up some boxes. Each box needs three pieces of tape, one as long as the long side and two as long as the short side. If Brian tapes up 5 boxes that measure 15 inches by 30 inches and 2 boxes that measure 40 inches square, how much tape does he need?


Reasoning and answer: The whole family consists of 4 + 2 + 1 = 7 persons. The entrance ticket to the park costs the same for every person, so the family would need to pay 7 * 5 = $35 to enter. For visiting the attraction the tickets would cost 4 * 2 = $8 for the kids. Their parents and grandmother would need to pay 3 * 4 = $12. That means a total cost for the family standing at 35 + 8 + 12 = $55.
The answer: 55

Question: In the city park, there are various attractions for kids and their parents. The entrance ticket to the park is $5, but for each attraction, you have to pay separately - such ticket costs $2 for kids and $4 for parents. How much would a family with 4 children, their parents, and her grandmother pay for visiting the park, and one attraction inside?


First find how many text messages he sent on Tuesday: 220 messages / 2 = 110 messages. Then find how many text messages he sent Wednesday - Friday: 50 messages / day * 3 days = 150 messages. Then add up all the messages he sent to find the total: 110 messages + 150 messages + 220 messages = 480 messages. Then divide that number by the number of days to find the average number of messages he sent per day: 480 messages / 5 days = 96 messages / day.
The answer: 96
Reverse engineering the question: Jason sent 220 text messages on Monday, half as many text messages on Tuesday, and 50 text messages each day Wednesday through Friday. How many text messages did he send on average during those five days?


The two t - shirts amount to $8 x 2 = $16. The two bags amount to $10 x 2 = $20. So Timothy spent $16 + $20 = $36 for the shirts and bags. He still has $50 - $36 = $14 left to spend for the key chains. With the money, he can buy $14 / $2 = 7 sets of key chains. Therefore, he can buy 7 x 3 = 21 pieces of key chains.
The answer: 21
Reverse engineering the question:
Timothy has $50 to spend at a souvenir shop. He sees some t-shirts that cost $8 each, key chains that sell 3 pieces for $2, and bags that cost $10 each. Timothy buys 2 t-shirts and 2 bags. How many pieces of key chains can he buy with the amount of money he has left?
