Reasoning and answer: Making the round trip to school means driving from the house to school and then back, for a total of 2.5 + 2.5 = 5 miles. He makes this trip twice in one day for a total of 2 * 5 = 10 miles. He does this 4 times in a week for a total of 4 * 10 = 40 miles. The round trip (once a week) to the market is 2 + 2 = 4 miles. His total mileage for a typical week = 40 + 4 = 44 miles.
The answer: 44

Question: John received 20 gifts on his 12th birthday. He received 8 fewer gifts on his 13th birthday. How many total gifts did he receive between those two birthdays?


He pays the minor characters 15000 * 4 = $60,000. The major characters each get 15000 * 3 = $45,000. So he pays the main characters 45,000 * 5 = $225,000. So in total he pays 225,000 + 60,000 = $285,000.
The answer: 285000
Reverse engineering the question: James runs a TV show and there are 5 main characters and 4 minor characters. He pays the minor characters $15,000 each episode. He paid the major characters three times as much. How much does he pay per episode?


Eating three times a day, a dog eats 3 * 4 = 12 pounds of food. Since there are 3 dogs at the camp, the total amount of food they eat is 3 * 12 = 36 pounds of food in a day. If each dog eats twice as much food as a puppy, a puppy will eat 4 / 2 = 2 pounds of food in one meal. Each puppy eats three times as often as a dog, and if a dog eats three times in a day, a puppy will eat 3 * 3 = 9 times in a day. Since a puppy eats 2 pounds of food a day, the total amount of food a puppy will eat in a day is 9 * 2 = 18 pounds of food. Four puppies in the camp eat 18 * 4 = 72 pounds of food every day. Together, the dogs and the puppies eat 72 + 36 = 108 pounds of food in a day.
The answer: 108
