user: Jack saves $10 / 2 = $5.00 a week. Over 8 weeks Jack saves $5.00 / week x 8 weeks = $40.00. In total Jack has $43.00 + $40.00 = $83.00 dollars in his piggy bank.
The answer: 83
Reverse engineering the question: Jack has $43 in his piggy bank. He also gets an allowance of $10 a week. If Jack puts half of his allowance into his piggy bank every week, after 8 weeks how much will Jack have in his piggy bank?
Reasoning and answer: He buys 3 bags of potato chips for $1.00 each so that’s 3 * 1 = $3.00. The chips are $3.00, the creme fraiche is $5.00 and the caviar is $73.00 for a total of 3 + 5 + 73 = $81.00. The appetizer costs $81.00 and will serve 3 people so it will cost 81 / 3 = $27.00 per person.
The answer: 27

Question: For a New Year’s Eve appetizer, Alex is serving caviar with potato chips and creme fraiche. He buys 3 individual bags of potato chips for $1.00 each and dollops each chip with some creme fraiche that costs $5.00 and then the $73.00 caviar. This appetizer will serve 3 people. How much will this appetizer cost per person?
The park has 42 / 3 = 14 pink crepe myrtle trees. It has 2 red trees, so it has 14 + 2 = 16 pink and red trees. Therefore, there are 42 - 16 = 26 crepe myrtle trees that have white flowers when they bloom in the park.
The answer: 26
Reverse engineering the question: A park has three colors of flowering crepe myrtle trees planted: red, white, and pink. When they bloom, a third of them are pink, but only two are red. Most of them are white. There are 42 crepe myrtle trees in the park. How many have white flowers when they bloom?
Reasoning and answer: First you must recognize that the problem involves finding the rate of how fast Ms. Alice can grade papers. To find how many papers she can grade in 11 hours, it would be useful to first find out how many papers she can grade in one hour. To do so, divide 296 papers by 8 hours, 296 / 8, to get 37. Therefore, Ms. Alice can grade 37 papers in one hour. To find out how many papers she can grade in 11 hours, multiply the number of papers she can grade in one hour by 11. 37 * 11 gives you 407. Ms. Alice can grade 407 papers in 11 hours.
The answer: 407

The town had 684 people then had a 25% growth spurt increasing the population by 684 * .25 = 171 people. The town had 684 people then they added 171 people bringing the population to 684 + 171 = 855 people. There were 855 people and 40% moved away so it decreased by 855 * .40 = 342. The population was 855 and 342 people moved away making the new population 855 - 342 = 513 people.
The answer: 513
Reverse engineering the question: Youngsville had a population of 684 people. The town had a growth spurt and the population increased by 25% then they witnessed that 40% of the population moved away. What is the current population?
Jacob has 5 * 30 = 150 insects. So, Angela has 150 / 2 = 75 insects.
The answer: 75
Reverse engineering the question:

assistant: Angela has half as many insects as Jacob does, and Jacob has 5 times as many insects as Dean. If Dean has 30 insects, how much does Angela have?
