Reasoning and answer: Lily spends $5 + $8 = $13 on celery and bread. Lily spends $12 * (50 / 100) = $6 on cereal. Lily gets 10% off the milk, so she pays 100% - 10% = 90% of its original price. Lily spends $10 * 90% = $9 on milk. She spends $1 * 6 = $6 on potatoes. Thus, she has $60 - $13 - $6 - $9 - $6 = $26 left over for coffee.
The answer: 26

Question: Lily goes to the supermarket. She has $60. She needs to buy 6 items: celery, cereal, bread, milk, potatoes, and coffee. She finds a stalk of celery for $5, cereal for 50% off $12, bread for $8, and milk for 10% off $10. She finds potatoes for $1 each and buys 6. How many dollars does she have left to spend on coffee?


Jessica’s papers weigh 8 * 1 / 5 = 8 / 5 ounces. The papers in the envelope weigh 8 / 5 + 2 / 5 = 10 / 5 = 2 ounces. Thus, Jessica needs 2 * 1 = 2 stamps to mail her letter.
The answer: 2
Reverse engineering the question: Jessica wrote a long letter to her aunt and needed to put stamps on it to mail it. She used eight pieces of paper that weigh 1/5 of an ounce each, and her envelope weighs 2/5 of an ounce. She needed one stamp per ounce. How many stamps did Jessica need to mail her letter?


Reasoning and answer: First, we find the number of hours per weekday by subtracting the smaller number time from the larger one, finding 10 - 4 = 6 hours per weekday. As there are 5 weekdays, this means the business is open 6 * 5 = 30 hours a week on the weekdays. Then we find out the amount of time the business is open on a weekend day, using the same process as we did with the weekdays, finding Jean's business is open 10 - 6 = 4 hours each weekend day. Since there are two weekend days, this means they are open 4 * 2 = 8 hours on the weekends. We add these two totals together to find that 30 + 8 = 38 hours per week.
The answer: 38

Question: If the normal hours of operation of Jean's business are 4 pm to 10p every day Monday through Friday, and from 6 pm to 10 pm on weekends, how many hours is the business open in a week?


First calculate the price of the two normally priced tickets by multiplying the price and the quantity: $50 * 2 = $100. Then calculate the scalper's initial asking price by multiplying the normal cost of two tickets by 240%: $100 * 2.4 = $240. Then subtract the $10 discount Jenna negotiated: $240 - $10 = $230. Now calculate the price of the discounted ticket Jenna's friend gets through her job by multiplying the normal ticket price by 60%: $50 * .6 = $30. Finally, add up the price of all the tickets to find the total: $100 + $230 + $30 = $360.
The answer: 360
Reverse engineering the question: Jenna is buying concert tickets for her group of five friends. She's able to get two of the tickets from the concert website for $50 each before they sell out. A scalper offers to sell her two more tickets for 240% of the normal price, but Jenna convinces him to give her $10 off that total payment. Finally, one of her friends gets a discounted ticket through her job for 60% of the normal price. How much do Jenna's friends pay for their tickets in total?


Reasoning and answer: Linda has 12 eggs left, 5 of which are brown, so 12 - 5 = 7 are white. Linda originally had 3 times as many white eggs as brown eggs, or 3 * 5 = 15 white eggs. So Linda broke 15 - 7 = 8 white eggs.
The answer: 8
What was the question?
Question: Linda was gathering eggs from her chicken coops. When she was done, she had three times as many white eggs as brown eggs. On her way back to the house, she stumbled, dropping her egg basket. Upon inspecting the damage, she found that all 5 of the brown eggs survived, but now she only had a dozen eggs left. How many eggs did Linda break?


Reasoning and answer: Let j be the length of Jake's snake and p be length of Penny's snake. We know that j + p = 70, and j = p + 12. We can substitute the second equation into the first equation to get p + 12 + p = 70. Combining like terms, we get 2p + 12 = 70. Subtracting 12 from both sides, we get 2p = 58. Dividing both sides by 2, we get p = 58 / 2 = 29 inches. Penny's snake is 29 inches. Substituting that length in to the equation j = p + 12, we get j = 29 inches + 12 inches = 41 inches.
The answer: 41

Question:
Jake and Penny are hunting snakes. Jake's snake is 12 inches longer than Jenny's snake. If the two snakes have a combined length of 70 inches, how long is Jake's snake?
