Q: Isabelle works in a hotel and runs a bubble bath for each customer who enters the hotel. There are 13 rooms for couples and 14 single rooms. For each bath that is run, Isabelle needs 10ml of bubble bath. If every room is filled to maximum capacity, how much bubble bath, in millilitres, does Isabelle need?
A: In the rooms for couples, there are 13 rooms * 2 people per room = 26 people. So in total, there are 26 people in couples' rooms + 14 people in single rooms = 40 people in the hotel. As each person gets a bubble bath, Isabelle will need a total of 40 baths * 10ml of bubble bath per bath = 400ml of bubble bath. The answer is 400.

[Question]At a station, a train comes every 5 minutes leaving 200 passengers and taking 320 others. How many different passengers step on and off a train at the station within an hour?
[Answer]At every passenger exchange there are 200 + 320 = 520 different people. One hour is 60 minutes, so during one hour, a train comes 60 minutes / hour / 5 minutes / train = 12 times. So during one hour, 12 trains * 520 passengers / train = 6240 different passengers step on and off the train. The answer is 6240.
Q: Ivory and Brayan are doing school projects with a tight deadline and have to stay up late to complete everything. They prepare coffee to help them stay focused. If Brayan drinks twice as much coffee as Ivory, and Brayan drinks 4 cups of coffee in an hour, calculate the total number of cups of coffee they drink together in 5 hours.
A: If Brayan drinks 4 cups of coffee in an hour, twice what Ivory drinks, then Ivory drinks 4 / 2 = 2 cups of coffee in an hour. Together, they drink 4 + 2 = 6 cups of coffee in an hour. After 5 hours, they will drink 5 * 6 = 30 cups of coffee together. The answer is 30.
Question: Tom decides to renovate a house. There are 3 bedrooms and each bedroom takes 4 hours to renovate. The kitchen takes 50% longer than each bedroom. The living room took twice as much time as everything else combined. How long did everything take?
Answer:
The kitchen took 4 * .5 = 2 hours longer than the bedrooms. So the kitchen took 4 + 2 = 6 hours. The bedrooms took 3 * 4 = 12 hours. So the kitchen and bedrooms combined took 12 + 6 = 18 hours. The living room took 18 * 2 = 36 hours. So everything took a total of 18 + 36 = 54 hours. The answer is 54.
