What was the question?
Question: Cristina, John, Clarissa and Sarah want to give their mother a photo album for her birthday. Cristina brings 7 photos, John brings 10 photos and Sarah brings 9 photos. If the photo album has 40 slots available, how many photos does Clarissa need to bring in order to complete the photo album?
The toys cost 5 * 3 = $15. His discount is worth 15 * .2 = $3. So he pays 15 - 3 = $12.
The answer: 12
Reverse engineering the question: John buys 5 toys that each cost $3. He gets a 20% discount. How much did he pay for everything?
Reasoning and answer: First find how many consonants are missing: 21 consonants * 1 / 7 = 3 consonants. Then add the number of missing vowels to find the total number of missing keys: 3 consonants + 2 vowels = 5 keys.
The answer: 5
What was the question?
Question: James' keyboard is missing 1/7 of the consonants and two vowels. How many keys are missing in total? (Remember there are 5 vowels and 21 consonants in the alphabet.)
She used 77 legos because 100 - 23 = 77. She made 11 levels because 77 / 7 = 11.
The answer: 11
Reverse engineering the question: Jade is building a lego tower. She has 100 pieces. Each level has to be 7 pieces wide. If she has 23 pieces left at the end, how many levels is her tower?
Reasoning and answer: The candy bars each cost $3 * 2 = $6. The cotton candies each cost 1 / 2 * (4 * $6) = $12. 6 candy bars cost 6 bars * $6 / bar = $36. 3 caramels cost 3 caramels * $3 / caramel = $9. All the candies together cost $36 + $9 + $12 = $57.
The answer: 57
What was the question?
Question: The price of candy bars is twice the cost of caramel, and the cost of cotton candy is half the price of 4 candy bars. If the price of 1 caramel is $3, how much do 6 candy bars, 3 caramel, and 1 cotton candy cost together?
Reasoning and answer: Let X be the amount owned by James. The amount owned by Ali is X - $40. The total amount owned by both of them X + (X - $40) = $250. Combining like terms, we get X * 2 - $40 = $250. Adding $40 to both sides, we get X * 2 = $290. Dividing both sides by 2, we get X = $145.
The answer: 145
What was the question?
Question:
James and Ali together own $250. If you know that James owns $40 more than Ali, then calculate the amount owned by James.
