Each iPhone X cost $600 so three iPhone Xs without the discount would cost 3 * $600 = $1800. The discount is 5% and 5% of $1800 is (5 / 100) * $1800 = $90 which is what they get to save by buying collectively.
The answer: 90
Reverse engineering the question: A smartphone seller is offering a discount of 5% off for customers who buy at least 2 smartphones at once. Melinda, Zoe and Joel want to buy an iPhone X each. If an iPhone X costs $600, how much can they save by pooling their money together and buying three iPhones at once from this seller rather than buying individually?

Question: Robie bought 3 bags of chocolates. She gave the 2 bags to her brothers and sisters then bought another 3 bags. How many bags of chocolates were left?


First find the total number of petunias: 4 flats * 8 petunias / flat = 32 petunias. Then find the total number of roses: 3 flats * 6 roses / flat = 18 roses. Now find how much fertilizer Seymour needs for the petunias: 32 petunias * 8 oz / petunia = 256 oz. Now find how much fertilizer Seymour needs for the roses: 18 roses * 3 oz / rose = 54 oz. Now find how much fertilizer Seymour needs for the Venus flytraps: 2 Venus flytraps * 2 oz / Venus flytrap = 4 oz. Now add up the fertilizer for all three plants: 256 oz + 54 oz + 4 oz = 314 oz.
The answer: 314
Reverse engineering the question: Seymour runs a plant shop. He has 4 flats of petunias with 8 petunias per flat, 3 flats of roses with 6 roses per flat, and two Venus flytraps. Each petunia needs 8 ounces of fertilizer, each rose needs 3 ounces of fertilizer, and each Venus flytrap needs 2 ounces of fertilizer. How many ounces of fertilizer does Seymour need in total?


Reasoning and answer: Allie has 9 - 1 = 8 toys of the same value. Without the value of the one $12 toy, all 8 other toys are worth in total 52 - 12 = $40. That would mean, that one of the other toys is worth 40 / 8 = $5.
The answer: 5
What was the question?
Question: Allie has 9 toys, which are in total worth $52. If we know that one toy is worth $12, and all the other toys have the same value, how much does one of the other toys cost?


He buys 2 packs of sandwich meat at $5.00 a pack so 2 * 5.00 = $10.00. He buys 2 packs of cheese at $4.00 a pack so 2 * 4.00 = $8.00. The loaf of bread cost $4.00 plus $10.00 for meat and $8.00 for cheese so his total is 4 + 10 + 8 = $22.00. He has coupons to use a checkout so his new total is 22 - 1 - 1 = $20.00. He can make 10 sandwiches from his purchase and his purchase total is $20 so 20 / 10 = $2.00.
The answer: 2
Reverse engineering the question: For every loaf of bread that Ted buys, he needs an additional 2 packs of sandwich meat and 2 packs of sliced cheese to make 10 sandwiches. The bread costs $4.00, the sandwich meat costs $5.00 per pack and the cheese costs $4.00 per pack. He has a $1.00 off coupon for one pack of cheese and an additional $1.00 coupon for one pack of meat. How much does each sandwich cost?


Eighteen hours later, after departing from London, Chance arrived in New York at 6:00 + 18 hours = 00:00 on Tuesday. If he arrived in cape town at 10:00 p.m. on Tuesday, his flight took 10:00 - 00:00 = 10 hours.
The answer: 10
Reverse engineering the question:
Chance boarded a plane departing from London to New York at 6:00 a.m. ET on Monday. He arrived in New York 18 hours later. If he took another plane flying to Cape town the day he arrived in New York and arrived in Cape town at 10:00 a.m ET on Tuesday, calculate the number of hours his flight took from New York to cape town.
