Q: A small airplane can seat 10 people in first class, 30 in business class, and 50 in economy class seating. If economy class is half full, and business class and first class have the same number of people together as economy class, how many seats are unoccupied in business class if only three people on the flight have first class seats?
A: There are 50 / 2 = 25 people in economy class. There are 25 people in business first and business class, so there are 25 - 3 = 22 in business class. Thus, there are 30 - 22 = 8 unoccupied seats in business class. The answer is 8.
Question: Donny saves $15 on Monday, $28 on Tuesday and $13 on Wednesday. On Thursday he spends half of his total savings so far. How much did he spend?

[Question]A frog pond has five frogs living in it. Some frogs laid eggs, and now there are three times as many tadpoles growing into more frogs as there are frogs. Two-thirds of the tadpoles will survive to maturity as frogs. The pond can only sustain eight frogs. How many frogs will have to find a new pond when the tadpoles grow up?
[Answer]There are three times the number of tadpoles as frogs, so there are 3 * 5 = 15 tadpoles. Two - thirds of the tadpoles will survive to become frogs, so 2 * 15 / 3 = 10 tadpoles will grow into frogs. When the tadpoles grow up, there will be 5 + 10 = 15 frogs in the pond. The pond can only sustain 8 frogs, so 15 - 8 = 7 frogs will need to find a new pond. The answer is 7.
Q: Emberly takes her mornings walks every day. If each walk takes her 1 hour covering 4 miles, and she didn't walk for 4 days in March, calculate the total number of miles she's walked.
A: In March, she walked for 31 - 4 = 27 days. If she walks for an hour a day, the total number of hours she'll walk in March is 27 days * 1 hour a day = 27 hours. If each walk is 4 miles, the number of miles she walked in March is 27 * 4 = 108 miles. The answer is 108.
Question: The average speed for an hour drive is 66 miles per hour. If Felix wanted to drive twice as fast for 4 hours, how many miles will he cover?
Answer: If Felix drives twice as fast, he will be covering 2 * 66 = 132 miles per hour. In four hours, driving at 132 miles per hour, since distance = speed * time, Felix will cover 132 * 4 = 528 miles. The answer is 528.
Q: Jane, Kyla, and Anthony have summer jobs in a resort. Their task is to fold guests' towels. Jane can fold 3 towels in 5 minutes. Kyla can fold 5 towels in 10 minutes, and Anthony can fold 7 towels in 20 minutes. If they all fold towels together, how many towels can they fold in one hour?
A:
There are 1 x 60 minutes = 60 minutes in 1 hour. There are 60 / 5 = 12 sets of 5 minutes in 1 hour. So, Jane can fold 3 x 12 = 36 towels in an hour. There are 60 / 10 = 6 sets of 10 minutes in 1 hour. So, Kyla can fold 5 x 6 = 30 towels in an hour. There are 60 / 20 = 3 sets of 20 minutes in 1 hour. So, Anthony can fold 7 x 3 = 21 towels in an hour. Therefore, the 3 of them can fold a total of 36 + 30 + 21 = 87 towels in 1 hour. The answer is 87.
