Fred received 250 + 120 = 370 stickers. Thus, Andrew shared 250 + 370 = 620 stickers. Therefore, Andrew kept 750 - 620 = 130 stickers.
The answer: 130
Reverse engineering the question: Andrew bought 750 stickers. He shared some of his stickers with his friends, Daniel and Fred. Daniel received 250 stickers, while Fred received 120 more stickers than Daniel. He kept the remaining stickers. How many stickers did Andrew keep?
Reasoning and answer: If Sue has 48 nuts, and Harry has twice as many nuts as Sue, Harry has 2 * 48 = 96 nuts. Bill has 6 times as many nuts as Harry, and since Harry has 96 nuts, Bill has 96 * 6 = 576 nuts. Combined, Bill and Harry have 576 + 96 = 672 nuts.
The answer: 672
What was the question?
Question: Bill has 6 times as many nuts as Harry, and Harry has twice as many nuts as Sue. If Sue has 48 nuts, how many do Bill and Harry have combined?
6 builders can build a single floor 6 builders / 3 builders = 2 times as fast as 3 builders. Thus 6 builders would build a single floor in 30 days / 2 = 15 days. There are 5 hours x 6 floors / house = 30 floors in total in 5 houses with 6 floors each. Therefore 6 builders would complete the project in 15 days / floor x 30 floors = 450 days. It would cost 450 days x $100 / day / builder * 6 builders = $270000 to complete the project.
The answer: 270000
Reverse engineering the question: Three builders build a single floor of a house in 30 days. If each builder is paid $100 for a single day's work, how much would it cost to hire 6 builders to build 5 houses with 6 floors each?
Reasoning and answer: First find the difference in hourly wages: $40 / hour - $30 / hour = $10 / hour. Then multiply that difference by the number of hours she works in a week to find the weekly difference: $10 / hour * 40 hours / week = $400 / week. Then multiply that amount by the number of weeks in a month to find the monthly difference in her earnings: $400 / week * 4 weeks / month = $1600 / month. Then find the total additional amount Janet pays in FICA taxes: $25 / week * 4 weeks / month = $100 / month. Then subtract Janet's extra FICA taxes and healthcare premium from the additional money she earns to find the net increase in her pay from freelancing: $1600 / month - $400 / month - $100 / month = $1100 / month.
The answer: 1100
What was the question?
Question: Janet is trying to decide whether to quit her job and start freelancing. She works 40 hours a week at both jobs. She get paid $30/hour at her current job, and would get paid $40/hour as a freelancer. However, she'd have to pay an extra $25 a week in FICA taxes plus $400/month in healthcare premiums. How much more would Janet make per month as a freelancer if there are four weeks in a month?
Pre - bought: 20 people * $155 = $3100. Gate bought: 30 people * $200 = $6000. $6000 - $3100 = $2900. The passengers that paid at the gate paid $2900 more dollars than those who pre - bought their tickets.
The answer: 2900
Reverse engineering the question: Twenty people pre-bought plane tickets at a price of $155 per ticket. Thirty people bought their plane tickets at the gate and they each paid $200 for their ticket. How many more dollars did the people at the gate pay for their tickets than those passengers that pre-bought their tickets?
Since each chapter of the book has 40 pages, Mitchell had read 10 * 40 = 400 pages from the first ten chapters. After reading 20 pages of the eleventh chapter, the total number of pages that Mitchell had read is 400 + 20 = 420. The next two chapters that she read had 2 * 40 = 80 pages. In total, Mitchell read 420 + 80 = 500 pages of the book that day.
The answer: 500
Reverse engineering the question:
Studying for her test, Mitchell had read ten chapters of a book before 4 o'clock. When it clocked 4, Mitchell had read 20 pages of the 11th chapter of the book she was studying from. After 4 o'clock, she didn't read the remaining pages of chapter eleven but proceeded and read 2 more chapters of the book. If each chapter in the book had 40 pages, calculate the total number of pages that Mitchell had read altogether?
