There are 4 puppies and 3 dogs at a camp. Each dog eats twice as much food as a puppy, but each puppy eats three times as often as a dog. If a dog eats 4 pounds of food three times a day, what would be the total amount of food the dogs and puppies eat in a day? Give the rationale and then the answer.
Let's think step by step. 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 is: 108.

Isabelle gets a job so she can save enough money to go to a concert with her two brothers. Her ticket costs $20. Her brothers both get the children’s discount, and each of their tickets cost $10. Her brothers have saved $5 between the two of them and Isabelle has saved $5. If her job pays $3 per week, how many weeks must she work to afford the tickets? Give the rationale and then the answer.
Let's think step by step. The tickets for both of her brothers will cost her $10 * 2 = $20. To buy tickets for all of them, it will cost Isabelle $20 + $20 = $40. Between all of them, they have saved a total of $5 + $5 = $10. Since they have already saved $10, she needs to earn an additional $40 - $10 = $30 to afford the tickets. Since she makes $3 per week, it will take her $30 / ($3 / week) = 10 weeks to save enough money for all of the tickets.. The answer is: 10.

John is lifting weights. He bench presses 15 pounds for 10 reps and does 3 sets. How much total weight does he move? Give the rationale and then the answer.
Let's think step by step. He presses 15 pounds x 10 reps = 150 pounds. He moves 3 sets x 150 pounds = 450 pounds in total.. The answer is: 450.
