Question: A store puts out a product sample every Saturday. The last Saturday, the sample product came in boxes of 20. If they had to open 12 boxes, and they had five samples left over at the end of the day, how many customers tried a sample if the samples were limited to one per person?
Answer: Step-by-step reasoning process: The store opened 12 boxes of 20 products, so they put out 20 * 12 = 240 product samples. They had 5 samples left over, so 240 - 5 = 235 samples were used. Each customer could only have one sample, so 235 * 1 = 235 customers tried a sample.
So the answer is 235.

Question: A particular train has some passenger cars and a number of cargo cars equal to half the number of passenger cars plus three. If the total number of cars is 71, counting the engine and caboose, how many passenger cars are in the train?
Answer: Step-by-step reasoning process: First find the number of cars not counting the engine and caboose: 71 cars - 2 cars = 69 cars. Let p be the number of passenger cars and c be the number of cargo cars. We know that p + c = 69 and c = p / 2 + 3. Substituting the second equation into the first, we get p + p / 2 + 3 = 69. Combining like terms, we get 1.5p + 3 = 69. Subtracting 3 from both sides, we get 1.5p = 66. Dividing both sides by 1.5, we get p = 44.
So the answer is 44.

Question: Chenny has 10 pieces of candies to be given out to her friends. She realized that she needs to buy 4 more so each of her friends will receive 2 candies. How many friends does Chenny have?
Answer: Step-by-step reasoning process: Chenny has a total of 10 + 4 = 14 candies. If each friend will receive 2 candies each, then she has 14 / 2 = 7 friends.
So the answer is 7.

Question: Milly's babysitter charges $16/hour. Milly is considering switching to a new babysitter who charges $12/hour, but also charges an extra $3 for each time the kids scream at her. If Milly usually hires the babysitter for 6 hours, and her kids usually scream twice per babysitting gig, how much less will the new babysitter cost?
Answer:
Step-by-step reasoning process: First figure out how much the first babysitter costs by multiplying her hourly rate by the number of hours she works: $16 / hour * 6 hours = $96. Then use the same method to figure out how much the second babysitter charges before any screaming: $12 / hour * 6 hours = $72. Then figure out how much the babysitter charges for two screams: 2 screams * $3 / scream = $6. Finally, subtract the second babysitter's two charges from the first babysitter's total charge to find the difference: $96 - $72 - $6 = $18.
So the answer is 18.
