Q: For every 1 minute that Carlotta sings on stage during the final opera performance, she spends an additional 3 minutes practicing and 5 minutes throwing temper tantrums. If her final stage performance is 6 minutes long, what is the total combined amount of time, in minutes, that she spends practicing, throwing tantrums, and singing in the final stage performance?
A: For each 6 minutes she performs, Carlotta spends 6 * 3 minutes = 18 minutes practicing. For each 6 minutes she performs, Carlotta throws tantrums for 6 * 5 minutes = 30 minutes. Thus, in total, for each 6 minutes of performance time, she spends 18 minutes + 30 minutes + 6 minutes = 54 minutes on all three activities. The answer is 54.
Question: Avery opens a flower shop. She ties 8 bunches of flowers with 9 flowers in each bunch. How many bunches would she have if she put 12 flowers in each bunch instead?

[Question]In the school's library, there are 2300 different books. 80% of all the books are in English, but only 60% of these books were published in the country. How many English-language books have been published outside the country?
[Answer]There are 80 / 100 * 2300 = 1840 books in English at the library. Out of these books, only 60 / 100 * 1840 = 1104 were published inside the country. So there are 1840 - 1104 = 736 books in English published outside of the country. The answer is 736.
Q: A carpenter is building a house. He needs 80 woodblocks to build it. If he has 8 logs that can make five woodblocks each, how many logs does the carpenter still need?
A: The carpenter initially has 8 x 5 = 40 blocks of wood. So he still lacks 80 - 40 = 40 blocks of wood. Therefore he still needs 40 / 5 = 8 logs of wood. The answer is 8.
Question: John uses 5 liters of fuel per km to travel. How many liters of fuel should John plan to use if he plans to travel on two trips of 30 km and 20 km?
