Each bottle of 2 liters of water costs $12 / 6 = $2. So the cost of 1 liter of water is $2 / 2 = $1.
The answer: 1
Reverse engineering the question: Six bottles of 2 liters of water cost $12. What is the price of 1 liter of water?


Reasoning and answer: First find the cost of the ticket and the entrée for each person: $50 / person + $10 / person = $60 / person. Then multiply that cost by the number of people to find the total cost of entrees and tickets: $60 / person * 6 people = $360. Now find how many people ordered drink tickets: 6 people / 2 = 3 people. Now find the total cost of the drink tickets: 3 people * $30 / person = $90. Now find the total cost of the evening: $90 + $360 = $450. Now multiply this quantity by 90% to find the amount of the refund: $450 * .9 = $405. Now subtract the refund amount from the total cost to find how much money the friends lost: $450 - $405 = $45.
The answer: 45

Question: Jenny signs up for dinner theater with 5 of her friends. Each person pays $50 for the ticket and $10 for their entrée, and half the people also buy unlimited drink tickets for $30/person. Then the dinner theater is canceled due to COVID, and each person gets a 90% refund. How much money did the group of six friends lose?


The research took 6 / 12 = .5 years. So it took 2 + .5 = 2.5 years for the first artifact. It takes 2.5 * 3 = 7.5 years for the second. So in total it took 2.5 + 7.5 = 10 years to find both.
The answer: 10
Reverse engineering the question: James decides to try and collect rare artifacts in the field. He spends 6 months researching before going on a 2-year-long expedition for his first find. The second artifact takes 3 times as long for the research and discovery. How long did it take him to find both?


Reasoning and answer: Lara can bake 5 x 6 = 30 cookies in one tray. So, Lara is baking a total of 30 x 4 = 120 cookies.
The answer: 120

Question: Lara is baking cookies using four baking trays. She places five rows of cookies on a baking tray where there are six cookies in one row. How many cookies is she baking?


There are 400 / 4 = 100 white homes in Belize. There are 400 - 100 = 300 non - white homes in Belize. There are 300 / 5 = 60 non - white homes that have a fireplace. There are 300 - 60 = 240 non - white homes that do not have a fireplace.
The answer: 240
Reverse engineering the question: The town of Belize has 400 homes. One fourth of the town's homes are white. One fifth of the non-white homes have a fireplace. How many of the non-white homes do not have a fireplace?


Maria has $120 and received $250 from her mother. So she has 120 + 250 = $370. As the price of the bike stands at $600, Maria needs 600 – 370 = $230 more to buy the bike.
The answer: 230
Reverse engineering the question:
Maria wants to buy a brand new bike. The retail price at the bike shop stands at $600. She saved $120 toward the purchase. As this was not enough, she asked her mother to give her the remaining amount. Her mother offered her $250 and told her that she needs to earn the rest working during the holidays. How much money must Maria earn to be able to buy the bike she wants?
