Reasoning and answer: After the first week, the fee will be $100 * 5% = $5. For the second week, the finance percentage will be 5% * 2 = 10%. George will have to pay a fee of $100 * 10% = $10 for the second week. In total, George will be charged $5 + $10 = $15 in fees.
The answer: 15

First figure out how much water all the pigs need: 8 pigs * 3 gallons / pig = 24 gallons. Then figure out how much water one horse needs by multiplying a pig's needs by 2: 3 gallons * 2 = 6 gallons. Now find how much water all the horses need: 10 horses * 6 gallons / horse = 60 gallons. Finally, add up all the animals' water needs: 24 gallons + 60 gallons + 30 gallons = 114 gallons.
The answer: 114
Reverse engineering the question: Carla needs to bring water to her animals. Each horse needs twice as much water as a pig, and the chickens drink from one tank that needs 30 gallons. How many gallons of water does Carla need to bring if she has 8 pigs and 10 horses and each pig needs 3 gallons of water?

Michelle kept 4 sandwiches * 2 = 8 sandwiches for herself. This leaves 20 total sandwiches – 4 sandwiches for a coworker – 8 sandwiches for herself = 8 sandwiches for her other co - workers.
The answer: 8
Reverse engineering the question: Michelle is bringing sandwiches to work to give to her co-workers. She gives 4 sandwiches to one of her co-workers and keeps twice this amount for herself. If she had originally made 20 sandwiches, how many sandwiches does she have left to give to her other co-workers?


Reasoning and answer: The first two tanks need 8 x 2 = 16 gallons of water. The other two tanks need 8 - 2 = 6 gallons of water each. So, the two other tanks need 6 x 2 = 12 gallons of water. Nicole needs 16 + 12 = 28 gallons of water every week for her four tanks. Therefore, she needs a total of 28 x 4 = 112 gallons of water in four weeks.
The answer: 112
