Question: Bert made 12 sandwiches for his trip. On the first day, he ate half of the sandwiches he made. The next day he ate 2 sandwiches less. How many sandwiches does Bert have left after these two days?
Answer: Step-by-step reasoning process: On the first day, Bert ate 12 / 2 = 6 sandwiches. The second day he ate 6 - 2 = 4 sandwiches. So in total Bert is left with 12 - 6 - 4 = 2 sandwiches.
So the answer is 2.

Question: A train leaves its departure station with 6 coal cars, 12 iron cars, and 2 wood cars. Between each station, there are 6 miles, and it takes 25 minutes to travel between them. At each station, the train can deposit up to 2 coal cars, 3 iron cars, and 1 wood car. How many minutes will it take to deliver all the cars?
Answer: Step-by-step reasoning process: To deliver all the coal, you need to pass by 6 coal / 2 coal / station = 3 stations. To deliver all the iron, you need to pass by 12 iron / 3 iron / station = 4 stations. To deliver all the wood, you need to pass by 2 wood / 1 wood / station = 2 stations. So 4 stations are needed to deliver everything, so 4 stations * 25 minutes / station = 100 minutes are needed.
So the answer is 100.

Question: The big bottles of mango juice hold 30 ounces and cost 2700 pesetas each. The small bottles hold 6 ounces and cost 600 pesetas each. How many pesetas would be saved by buying a big bottle instead of smaller bottles for the same volume of juice?
Answer: Step-by-step reasoning process: The equivalent is 30 / 6 = 5 small bottles. Five small bottles at 600 pesetas each is 5 * 600 = 3000 pesetas. The savings is 3000 - 2700 = 300.
So the answer is 300.

Question: Christy and her friend Tanya go to Target to buy some face moisturizer and body lotions. Christy spends twice as much as Tanya, who pays 50$ for two face moisturizers each and 60$ per body lotion, buying four of them. How much money did they spend together in total?
Answer:
Step-by-step reasoning process: The total amount Tanya spent on face moisturizers is 50 * 2 = $100. If she bought four body lotions, the total cost is 4 * 60 = $240. Tanya spent a total of 240 + 100 = $340 in the store. If Christy spent twice this amount, the total was 2 * 340 = $ 680. The total amount of money they both spent is 680 + 340 = 1020$.
So the answer is 1020.
