He spent 20 - 8 = $12 on Slurpees. So he got 12 / 2 = 6 Slurpees.
The answer: 6
Reverse engineering the question: John goes to the store to buy Slurpees and gives them $20. Slurpees cost $2 each and he got $8 in change. How many Slurpees did he buy?
Reasoning and answer: The chest of drawers sold for half as much as the treadmill, for a price of $100 / 2 = $50. The television sold for three times what he earned for the treadmill, for a price of $100 * 3 = $300. For the three items, he raised $100 + $50 + $300 = $450. If $450 is 75% of the total sum of money that Toby made at the garage sale, then the total amount is $450 / (75 / 100) = $600.
The answer: 600

Question: Toby held a garage sale to raise money to support friends who have lost their jobs. Of all the items that he sold during the garage sale, three of the items he sold made up 75% of the total amount of sales money he earned. He sold a treadmill for $100, a chest of drawers for half as much as he made for selling the treadmill, and he sold a television for three times what he earned for selling the treadmill. What is the total sum of money, in dollars, that Toby made at the garage sale?
Herman buys himself and 3 team members breakfast 5 days a week so that's 4 * 5 = 20 breakfast combo meals. Each combo meals costs $4.00 and he buys 20 of them a week so that's 4 * 20 = $80.00. Over a 16 week period he spends 16 * 80 = $1,280.00 on breakfast.
The answer: 1280
Reverse engineering the question: When Herman's team is busy working on large projects he stops at the drive-through 5 days, every week to buy a breakfast combo for himself and 3 members of his team. Each meal costs $4.00. This current project will last 16 weeks. How much will Herman spend on breakfast?
Reasoning and answer: She stocks one roll in each of the 6 bathrooms, every day of the week so that 6 * 7 = 42 rolls a week. She restocks 42 rolls a week so after 4 weeks that's 42 * 4 = 168 rolls. The bulk toilet paper comes 1 dozen rolls in a pack and she needs 168 rolls so she needs 168 / 12 = 14 dozen.
The answer: 14

Question: Part of Stella's job is to restock the toilet paper in each of the 6 bathrooms at the bed and breakfast. She stocks 1 roll a day, every day of the week. She buys the toilet paper in bulk, and each pack contains 1 dozen rolls. After 4 weeks, how many packs of toilet paper dozen Stella buy?
Her errands include a 30 min commute and 30 min grocery shopping, 10 min for dry cleaning and 20 min to grab the dog for a total of 30 + 30 + 10 + 20 = 90 minutes. Her errands took 90 minutes and she has another 90 minutes of cooking for a total of 90 + 90 = 180 minutes of chores / errands. 60 minutes are in 1 hour and she has 180 minutes of work so that's 180 / 60 = 3 hours. She is off of work at 4:00 pm and has 3 hours of errands / chores so she won't be able to eat until 4 + 3 = 7:00 pm.
The answer: 7
Reverse engineering the question: Jasmine gets off of work at 4:00 pm. After that, it will take her 30 minutes to commute home, 30 minutes to grocery shop, 10 minutes to pick up the dry cleaning, 20 minutes to pick up the dog from the groomers and 90 minutes to cook dinner when she returns home. What time will she eat dinner?
Conor can chop 12 x 4 = 48 eggplants a week. He can chop 9 x 4 = 36 carrots a week. He can chop 8 x 4 = 32 potatoes a week. Therefore, Conor can chop 48 + 36 + 32 = 116 vegetables a week.
The answer: 116
Reverse engineering the question:
Conor can chop 12 eggplants, 9 carrots, and 8 potatoes in a day. If he works 4 times a week, how many vegetables can he chop?
