First find the total number of blisters on Brenda's arms: 60 blisters / arm * 2 arms = 120 blisters. Then add the blisters on the rest of her body to find the total: 120 blisters + 80 blisters = 200 blisters.
The answer: 200
Reverse engineering the question: Brenda catches smallpox. She has 60 blisters on each arm and 80 blisters on the rest of her body. How many blisters does she have in total?


Reasoning and answer: Up, took 12 / 4 = 3 hours. Down, took 12 / 6 = 2 hours. Total time was 3 + 2 = 5 hours.
The answer: 5

Question: Jeannie hikes the 12 miles to Mount Overlook at a pace of 4 miles per hour, and then returns at a pace of 6 miles per hour. How long did her hike take, in hours?


First find the total number of chicks: 40 pigeons * 6 chicks / pigeon = 240 chicks. Then add that to the number of adult pigeons to find the total number of pigeons: 240 chicks + 40 pigeons = 280 pigeons. Then multiply that number by 30% to find the number of pigeons that were eaten: 280 pigeons * 30% = 84 pigeons. Then subtract that number from the total number of pigeons to find the number that are left: 280 pigeons - 84 pigeons = 196 pigeons.
The answer: 196
Reverse engineering the question: There are six peregrine falcons and 40 pigeons nesting in Malcolm's skyscraper. Each pigeon has 6 chicks. If the peregrines eat 30% of the pigeons, how many pigeons are left?


Reasoning and answer: The cookies cost 3 x .5 = 1.5. The hamburgers cost $7.3 because 2 x 3.65 = 7.3. The total cost is $16 because 7.3 + 2 + 1 + 4 + 1.5 + .2 = 16. The cost is $8 per person because 16 / 2 = 8. Toby has $7 in change because 15 - 8 = 7.
The answer: 7

Question: Toby is dining out with his friend. They each order a cheeseburger for $3.65. He gets a milkshake for $2 and his friend gets a coke for $1. They split a large fries that cost $4. His friend also gets three cookies that cost $.5 each. The tax is $.2. They agree to split the bill. If Toby arrived with $15, how much change is he bringing home?


Mark has 50 / 100 * 6 = 3 points more than Eric. So Mark has 6 + 3 = 9 points. That means Samanta has 9 + 8 = 17 points. So in total Samanta, Mark, and Eric have 6 + 9 + 17 = 32 points.
The answer: 32
Reverse engineering the question: In a game, Samanta has 8 more points than Mark, and Mark has 50% more points than Eric. Eric has 6 points. How many points do Samanta, Mark, and Eric have in total?


There are 4 tables, 1 sofa and 2 chairs that have 4 legs each so 4 + 1 + 2 = 7 pieces of furniture. These 7 pieces have 4 legs each so they have 7 * 4 = 28 legs. There are 3 tables with 3 legs each so they have 3 * 3 = 9 legs. We have 28 legs and 9 legs as well a 1 leg on a table and 2 on a rocking chair for a total of 28 + 9 + 1 + 2 = 40 legs.
The answer: 40
Reverse engineering the question:
There is a very large room that has 4 tables, 1 sofa and 2 chairs that have 4 legs each. There are also 3 tables with 3 legs each, 1 table with 1 leg, and 1 rocking chair with 2 legs. How many legs are there in the room?
