Question: The population of Mojave was 4000 a decade ago. If the town's population has increased three times, and the population analysis firm predicts that it will increase by 40% after five years, how many people will be in Mojave in five years?
Answer: Since the population of Mojave has increased three times the number it was a decade ago, there are 3 * 4000 = 12000 people in Mojave now. It's predicted that the population will increase by 40 / 100 * 12000 = 4800 people after five years. This means there will be 12000 + 4800 = 16800 people living in Mojave in five years. The answer is 16800.

[Question]Flora has been experiencing frequent fractures. Dr. Juan has asked her to strengthen her bones by drinking 105 gallons of milk within 3 weeks. Flora thinks that drinking 3 gallons of milk daily will be enough, but her brother says she'll still need to drink more. To fulfill Dr. Juan’s requirement, how many more gallons must Flora drink daily?
[Answer]3 weeks translate to 3 * 7 days = 21 days. To meet Dr. Juan’s recommendation would mean drinking 105 / 21 = 5 gallons daily. This means that Flora must drink 5 - 3 = 2 more gallons daily. The answer is 2.
[Question]Tara is saving up to buy a new clarinet. She already has $10 saved. The clarinet costs $90. She plans to sell her old books to make the money. She sells each book of hers for $5. However, when she is halfway towards her goal, she loses all her savings and has to start over. How many books does she sell in total by the time she reaches her goal?
[Answer]
Halfway towards her goal is $45 because 90 / 2 = 45. She sells $35 worth of books before she loses the money because 45 - 10 = 35. She sells 7 books before losing her money because 35 / 7 = 5. She then sells 18 books because 90 / 5 = 18. She sells 25 books in total because 18 + 7 = 25. The answer is 25.
