Lisa spends $40 on t - shirts / 2 = $20 on jeans. She also spends $40 on t - shirts * 2 = $80 on coats. So Lisa has spent a total of 40 + 20 + 80 = $140. Carly spends $40 / 4 = $10 on t - shirts. She also spends $20 per pair of jeans * 3 = $60 on jeans. She then also spends $80 Lisa's cost for coats / 4 = $20 on coats. So Carly has spent a total of 10 + 60 + 20 = $90. Lisa and Carly have therefore spent a total of 140 + 90 = $230.
The answer: 230
Reverse engineering the question: Lisa and Carly go shopping together. Lisa spends $40 on t-shirts then spends half of this amount on jeans and twice this amount on coats. Carly spends only a quarter as much as Lisa on t-shirts but spends 3 times as much on jeans and a quarter of the amount Lisa spent on coats. In dollars, how much did Lisa and Carly spend in total?
Reasoning and answer: There are 3 bouquets. The total is the average times the number of bouquets, or 12 * 3 = 36. There are 9 + 14 = 23 accounted for. The third included 36 - 23 = 13 carnations.
The answer: 13
What was the question?
Question: Trevor buys three bouquets of carnations. The first included 9 carnations, and the second included 14 carnations. If the average number of carnations in the bouquets is 12, how many carnations were in the third bouquet?
The price of the washing machine is $4275 - $1490 = $2785. The total price of the purchases is $4275 + $2785 = $7060.
The answer: 7060
Reverse engineering the question: Your mom bought a refrigerator and a washing machine. Note that the price of the refrigerator is $4275 and the price of the washing machine is $1490 less than the price of the refrigerator. Calculate the total price of the purchases in dollars.
Reasoning and answer: Jennifer has 2 * 10 = 20 apples. She has a total of 10 + 20 + 20 = 50 fruits. She gives her sister 2 pears + 2 oranges + 2 apples = 6 fruits. After giving her sister 2 of each fruit, she has 50 - 6 = 44 fruits left.
The answer: 44
What was the question?
Question: Jennifer has ten pears, 20 oranges, and twice as many apples as pears. If she gives her sister two of each fruit, how many fruits does she have left?
Before washing the car Fred had $14 - $6 = $8. Fred spent half his allowance for the movies, so 2 * $8 = $16 allowance.
The answer: 16
Reverse engineering the question: Fred spent half of his allowance going to the movies. He washed the family car and earned 6 dollars. What is his weekly allowance if he ended with 14 dollars?
A third of $30 is $30 * (1 / 3) = $10. She spent $10 from $30 leaving $30 - $10 = $20. She spent another $8 leaving $20 - $8 = $12 which she saved.
The answer: 12
Reverse engineering the question:
Annabelle collected a weekly allowance of $30. She spent a third of it buying junk food, then spent another $8 on sweets. Out of guilt she decides to save the rest. How much did she save?
