Question: There are 4 carriages in a train and each carriage has 25 seats. If each carriage could accommodate 10 more passengers, how many passengers would fill up 3 trains?
Answer: Step-by-step reasoning process: If each carriage had another 10 seats, each carriage would have 25 + 10 = 35 seats. The train comprises of 4 carriages and each carriage now has 35 seats; therefore a train has 35 x 4 = 140 seats. 3 trains with 140 seats each in total can take up 3 x 140 = 420 passengers.
So the answer is 420.

Question: Mrs. Anderson bought 2 bags of 3-pound bag of cat food and another 2 bags of dog food that each weigh 2 more pounds than each bag of cat food. There are 16 ounces in each pound. How many ounces of pet food did Mrs. Anderson buy?
Answer:
Step-by-step reasoning process: The two bags of cat food weigh 2 x 3 = 6 pounds. Each bag of dog food weighs 3 + 2 = 5 pounds. So two bags of dog food weigh 2 x 5 = 10 pounds. Thus, Mrs. Anderson bought 6 + 10 = 16 pounds of pet food. And 16 pounds is equal to 16 x 16 = 256 ounces.
So the answer is 256.
