Saturday's total was 2 * 40 - 10 = 70. Sunday's was 70 / 2 = 35. The sum is 40 + 70 + 35 = 145.
The answer: 145
Reverse engineering the question: Tameka is selling boxes of crackers for her scout troop. On Friday, she sold 40 boxes. On Saturday, she sold 10 fewer than twice that number. And on Sunday, she sold half as many as Sunday. How many boxes did she sell over the three days?
Reasoning and answer: Her cash back app gave her 10% back on $150.00 so that's .10 * 150 = $15.00 cash back. She received $15.00 from the cashback app and has a $25.00 mail - in rebate for a total of 15 + 25 = $40.00 discounts. She spent $150.00 for the medicine and has $40.00 worth of discounts so the medicine will cost 150 - 40 = $110.00.
The answer: 110

Tom's rabbit is 8 / 2 = 4 years old. His dog is 4 x 3 = 12 years old.
The answer: 12
Reverse engineering the question: Tom's cat is 8 years old. His rabbit is half the age of his cat. His dog is three times as old as his rabbit. How old is the dog?
Reasoning and answer: Tommy's area is 5 blocks wide because 3 + 2 = 5. His area is 4 blocks tall because 2 + 2 = 4. The total area is 20 square blocks because 5 x 4 = 20. His friend's area is 4 times bigger because 80 / 20 = 4.
The answer: 4

Question: Tommy's mother lets him ride his bike 2 blocks north of his block, 3 blocks east, 2 blocks west, and 2 blocks south. His friend's father lets his friend ride his bike 80 square blocks. How many times greater is the area his friend can ride in compared to Tommy?
The difference in age between Joel and his dad is 32 - 5 = 27 years. When you double this gap in years, you have 27 x 2 = 54. When his dad is 54, Joel will be 54 / 2 = 27 years old.
The answer: 27
Reverse engineering the question: Joel is 5 years old and his dad is 32 years old. How old will Joel be when his dad is twice as old as him?
The rectangular tables seat 7 * 10 = 70 pupils. The square tables will seat 90 - 70 = 20 pupils. The library needs 20 / 4 = 5 square tables.
The answer: 5
Reverse engineering the question:
A library has 7 rectangular tables and the remaining tables will be square tables. A rectangular table seats 10 pupils while a square table seats 4 pupils. How many square tables are needed so that 90 pupils can read at the same time?
