The total number of apples delivered was: 180 apples x 12 crates = 2160 apples. So, the number of remaining apples after throwing away the rotten ones was: 2160 apples 160 apples = 2000 apples. And now, we can find the total number of boxes of apples by dividing the remaining number of apples by the number of apples per box: 2000 apples / 20 apples / box = 100 boxes of apples.
The answer: 100
Reverse engineering the question: There were 180 apples in each crate. 12 such crates of apples were delivered to a factory. 160 apples were rotten and had to be thrown away. The remaining apples were packed into boxes of 20 apples each. How many boxes of apples were there?
Reasoning and answer: First find the cost of the two used computers: $200 / computer * 2 computers = $400. Then subtract that cost from the cost of the new computer to find the savings: $600 - $400 = $200.
The answer: 200

Question: James can buy a new computer for $600 and have it last 6 years, or buy 2 used computers for $200 each that each last 3 years. How much money will he save by picking the cheaper option?
On Monday there are 20 / 100 * 25 = 5 cars passing the street less than on Tuesday. So on Monday, there are 25 - 5 = 20 cars on Happy Street. On Wednesday, there are 20 + 2 = 22 cars on this street. On Thursday and Friday, there is a total of 10 * 2 = 20 cars passing. On the weekend 5 * 2 = 10 cars are passing. So from Monday through Sunday, there are 20 + 25 + 22 + 20 + 10 = 97 cars traveling down the street.
The answer: 97
Reverse engineering the question: There is very little car traffic on Happy Street. During the week, most cars pass it on Tuesday - 25. On Monday, 20% less than on Tuesday, and on Wednesday, 2 more cars than on Monday. On Thursday and Friday, it is about 10 cars each day. On the weekend, traffic drops to 5 cars per day. How many cars travel down Happy Street from Monday through Sunday?
Reasoning and answer: In the full decks, John has a total of 52 cards in a full deck of cards * 3 full decks of cards = 156 cards. A half - full deck of cards contains 52 cards in a full deck of cards / 2 = 26 cards. So from the half - full decks, John has a total of 26 cards * 3 half - full decks = 78 cards. This is a total of 156 cards from full decks + 78 cards from half - full decks = 234 cards. After throwing some in the trash, he now holds a total of 234 cards - 34 trashed cards = 200 cards.
The answer: 200

Question: John is holding a poker night with his friends and is getting the decks of cards ready before his friends show up. After losing so many cards from various decks, John thinks he needs to count exactly how many cards he has to make sure he has enough full decks for the night. Each deck of cards should hold 52 cards. He finds 3 half-full decks of cards and 3 full decks of cards. As he is arranging them, he realizes that the quality of a lot of the cards is quite poor and decides to throw 34 of the cards in the trash. How many cards does John now have?
They'll need to make an estimated 0.5 * 53 = 26.5 omelets for small children. They'll need to make an estimated 1 * 35 = 35 omelets for older children. They'll need to make an estimated 2 * 75 = 150 omelets for the adults. And they'll need to make an estimated 1.5 * 37 = 55.5 omelets for the seniors. Along with the 25 extra omelets they'll make as a buffer, they will need enough eggs for 26.5 + 35 + 150 + 55.5 + 25 = 292 omelets. So they will need 2 * 292 = 584 eggs.
The answer: 584
Reverse engineering the question: The Rotary Club is holding its annual fundraising Omelet Breakfast, with tickets sold in advance. The tickets come in different price levels, for young children, older children, adults, and seniors. This year they sold 53 small children tickets, 35 older children tickets, 75 adult tickets, and 37 senior tickets. To figure out how many eggs they need to buy, the club estimates that small children can eat a half omelet, older children can eat a whole omelet, adults will eat two omelets, and seniors will eat one and a half omelets. Just to be on the safe side, they get enough eggs to make 25 extra omelets. If they use 2 eggs for each omelet, how many eggs will they need to buy?
First find the number of votes for the unicorn cake: 7 votes * 3 = 21 votes. Then find the number of votes for the dragon cake: 25 votes + 7 votes = 32 votes. Then add the number of votes for each cake to find the total number of votes: 21 votes + 32 votes + 7 votes = 60 votes.
The answer: 60
Reverse engineering the question:
In the baking contest, three times as many people voted for the unicorn cake compared to the witch cake, and the number of votes for the dragon cake was 25 more than the number of votes for the witch cake. If 7 people voted for the witch cake, how many votes were cast total?
