To achieve her goal, she must read 140 / 7 = 20 pages per day. She planned to read 3 * 6 = 18 pages daily. She must read 20 - 18 = 2 more pages per day.
The answer: 2
Reverse engineering the question: While planning to finish reading a 140-page book in one week, Jessy initially decides to read 3 times daily, 6 pages each time, every day of the week. How many more pages should she read per day to actually achieve her goal?


Reasoning and answer: The number of blocks in each walk around the neighborhood is 4 blocks + 7 blocks + 11 blocks = 22. Ray's dog walks 3 walks × 22 blocks / walk = 66 blocks each day.
The answer: 66
What was the question?
Question: Ray always takes the same route when he walks his dog. First, he walks 4 blocks to the park. Then he walks 7 blocks to the high school. Finally, he walks 11 blocks to get back home. Ray walks his dog 3 times each day. How many blocks does Ray's dog walk each day?


He wants to save $1,000.00 and he has $100.00 left over so he still needs to save 1000 - 100 = $900.00. He wants to save $900.00 over 12 months so that means he needs to save 900 / 12 = $75.00 per month.
The answer: 75
Reverse engineering the question: Alfred likes to save $1,000.00 over 12 months for his Christmas shopping. He has $100.00 left over from last year's holiday to put towards this year's goal. How much money does Alfred now need to save each month in order to reach his goal in 12 months?


Reasoning and answer: The quilt is made of 16 squares on one side and 16 on the other so 16 + 16 = 32 squares total. She has already sewn 25% of the quilt so she has sown together .25 * 32 = 8 squares. Betsy still has 32 - 8 = 24 more squares to sew together.
The answer: 24
What was the question?
Question: Betsy is sewing a quilt. The quilt is made up of 16 squares sewn together on one side and 16 squares sewn together on the other side. Betsy has already sewn 25% of the quilt together. How many more squares does she need to sew together?


First find the number of spiral shells Jackson collects: 45 hermit crabs * 3 spiral shells / hermit crab = 135 spiral shells. Then find the number of starfish he collects: 135 spiral shells * 2 starfish / spiral shell = 270 starfish. Then add the number of each animal he collects to find the total number: 135 spiral shells + 270 starfish + 45 hermit crabs = 450 souvenirs.
The answer: 450
Reverse engineering the question: Jackson collects 45 hermit crabs, 3 spiral shells per hermit crab, and 2 starfish per spiral shell. How many souvenirs does he collect total?


He works 8 hours a day for 10 days means he works 8 * 10 = 80 hours. It takes him 5 hours to build one rocking chair so over 80 hours he builds 80 / 5 = 16 rocking chairs.
The answer: 16
Reverse engineering the question:
Ben works 8-hour shifts in a furniture shop. It takes him 5 hours to build 1 rocking chair. How many chairs can he build in 10 days?
